She knew she was always jealous of her daughter, but didn't know she'd be willing to destroy her kid's hard-earned school project. 

Mama bear mode got activated when she caught the malicious saboteur red-handed.

  • [I threw] my daughters friend out of our house because she RUINED a major school project

    I (36F) am having a huge argument with another mom in my neighborhood, and i really need to know if i took things too far.

  • My daughter (15F) has a friend the same age. They hang out a lot, but this friend has a weird habit of getting jealous. If my daughter gets a good grade or a new phone, the friend gets super moody and quiet.

  • This 36-year-old's teenage daughter was a superstar. She knew it, her family knew it, and her daughter's friend apparently knew it, too, except the teen girl's friend was more than a little jealous of her “friend's” successes. Vindictively, the girl took action against her friend, most likely to knock her down a few pegs, sabotaging a project she had worked on for 3 long weeks; however, she didn't expect the consequences of her pathetically malicious plan. 

  • So basically, my daughter has been working on a massive diorama for her history class for the past 3 weeks. It took a lot of hard work, money for supplies, and late nights. Yesterday, the friend came over after school to hang out.

  • sticky, dark cherry juice all over my daughters diorama. It was completely destroyed and soggy.

  • The friend immediately tried to say she tripped. But there was absolutely nothing on the floor to trip on, and she was standing totally still. The glass was completely empty, like she poured it on purpose.

  • My daughter was sobbing, saying the friend did it bcoz she was failing history and had not even started her own project yet.
    via Rude-Discipline199
  • I just saw red, i told the friend to grab her backpack and get out of my house right that second. I did not scream or curse, but i was very strict and did not let her argue with me. I opened the front door and stood there until she walked out.

  • GET OUT. 

    Any parent would protect their teenager in this way; however, when this protective mother brought down the hammer on her daughter's friend, a compulsive liar, she should have anticipated some fallout on the parental side. Regardless, in the moment, and when she was watching cherry juice drip all over her daughter's project and onto the cream carpet, kicking the girl to the curb was the most mild, level-headed approach. 

  • About an hour later, her mom called me. She was screaming on the phone, saying i traumatized her kid over a simple, stupid mistake. She said i had no right to throw a minor out and demanded a huge apology.

  • I refused to apologize, i actually told her she needs to pay me back for the ruined art supplies.

    via Rude-Discipline199
  • TL;DR: My daughters friend got jealous and purposely poured dark juice all over my daughters school project that took weeks to make. I immediately made the friend leave my house. Now her mom is furious, refusing to pay for damages, and calling me a bu y.

  • The malicious teenager obviously lied to her own mom, spinning a web that made her look favorable in the eyes of the pittiless, but the mom knew the truth. She wouldn't let this mean girl stomp all over her daughter's shine anymore, and after this incident, she hoped that her daughter would see that too. 

    Sometimes, "friends" in your teenage years are far from real friends, and instead of having your back, they sabotage you. One of my alleged best friends in high school was exactly like this girl: Envious, mean, and spiteful. For a long time, I dimmed my sparkle around her so that she would feel okay about failing classes, getting in trouble, and being a bit of a delinquent, but finally I realized that she was not only bringing me down, but she was sabotaging me on purpose. 

    Drop friends like that, or just hope that you have a mom who's awesome enough to teach them a lesson on your behalf.

  • OP R de-Discipline199 Honestly. it was the audacity for me. she did not even look sorry when she did it.

  • ashatteredteacup You're a great parent. I'm sorry about the project. Please send all evidence and information to school and of the girl's attitude, hopefully the teachers can separate them as well. Your child will always remember you having her back. NTJ

  • OP R de-Discipline199 Exactly. i'm definitely letting the school know. its not just about the project, its the fact that she did it on purpose while looking my daughter in the face. i wont let anyone treat my kid like that in her own home.

  • Long_Ad3737 NTA, that was sabotage, you handled it chill

  • OP R de-Discipline199 Thanks. it literally broke my heart seeing my daughter cry like that after working so hard for weeks. i just could not stand having that girl in my house for another second.

  • No-Refrigerator-2694 If the friend was already jealous and failing, this feels very on- purpose. Your daughter deserved to see you have her back. The other mom def owes you for supplies at minimum.
    via No-Refrigerator-2694
  • OP R de-Discipline199 Thank you for saying that. my daughter was so heartbroken. seeing her face when she saw the mess just broke me. im glad i stood my ground bcoz she needed to know im on her side.

  • Careless-Image-885 NTJ. Actions have consequences. You did the right thing. If you haven't already, take pictures of the damage. Try to salvage what you can or build anew. Sit down with your daughter and explain that this girl is toxic and NOT a friend. If your daughter didn't understand how much you love her and will protect her, she does now. Explain that you don't want this girl in your home ever again. This girl is a bu y, hugely jealous and has some real issues going on. Judging from her mo

  • OP R de-Discipline199 Honestly, you are right. I kept making excuses for her thinking it was just teen girl drama and that she grow out of it. Huge mistake on my part. I already told my daughter they are done, and that girl is never stepping foot in our house again. My daughters peace of mind comes first now.

  • Usual-Canary-7764 So this friend is always weirdly jealous and the friendship has been encouraged because? You did not see something like this coming? YTA for not stopping it sooner...NTA for all of the rest that happened. That friend would not be welcome in my house ever again. Both she and her mother are definitely cut from the same cloth when you see those reactions. Now OP what are you going to do to protect your daughter?
    via Careless-Image-885
  • OP R de-Discipline199 I totally agree. The way her mom acted on the phone really explained everything. No apology, just excuses for her daughters behavior. Its sad, but you are right, the apple does not fall far from the tree. That girl is definitely banned from our house for good.

  • JaJoSam Take a picture of her diorama so the teacher and that mother can see it. Perhaps the teacher will give your daughter time to recreate her work.

  • RedReaper666YT NTJ - not only do actions have consequences, the girl's 15 not 5. Walking herself home at that age is entirely appropriate. Don't let that kid back in your house, like, ever!
