There comes a time in every kid's life where they need to start being held accountable for their actions and decisions. Usually that age is around 1st or 2nd grade, because children are learning the difference between right and wrong. So when her parents were still coddling this 19-year-old after turning the page on her childhood, this 33-year-old older brother was ready to bring the swift hammer of accountability down—especially after she endangered one of his prize-winning horses.

  • I'm not a horse girl by any means, but I appreciate the beasts. Enormous and generally mild-mannered, horses are a strange part of human society that's just been normalized over centuries of domestication. If you'd never seen a horse before, and one charged at you in the wild, in all likelihood, a human would be scared for their life. They're gigantic, powerful animals—so what's stopping them from kicking your head in or trampling you like a bug? Well, this teenager forgot that horses aren't just docile little critters we have lounging around the ranch; they're big, potentially dangerous creatures that should be taken seriously. 

    Well, after this egregious and childish act of rebellion, she'll probably never see the inside of a horse stable again. 

  • "AITA for sending my little sister a vet bill after she tried to get my horses to breed?"

  • alsotheabyss Horse owner, absolutely NTA. WHAT THE F I WAS SHE THINKING. He could have k lled your mare! Bet she wouldn't like that bill, or the lost income afterwards.

  • lovinglifeatmyage Ex horse owner here Please tell us your not having your sister work in your yard again, she's an absolute menace by the sounds of it.
    via lovinglifeatmyage
  • And yes, she should be paying the vet bill. Hopefully that will make her realise what she did NTA

  • Performance_Lanky INFO: How much is the bill? PedoffEquestrian £1100 and they're lucky it's that low.

  • This was monumentally disrespectful and potentially harmful to your horses. Regardless of if you had a planned br ling or not, you were correct to keep the new stallion separated until you knew what's what.

  • Horses have so many communicable viral and bacterial diseases they can spread to each other. And you were right not to want to risk your other horses. Not to mention, he could have severely injured your mare.

  • Your sister needs to learn to listen when she is told "no" and not to do things just because she thinks it would be "cute." I would be upset about it as well (I'm actually secondhand upset for you!), and her having to deal with the consequences of her actions is right.
    via gingrbreadandrevenge
  • Your parents' reaction is EXACTLY why your younger sister feels like she can get away with whatever she likes and then boo-hoo and claim ignorance. Let them know that if they keep coddling her, the next call might be from the police when she does something even worse because, for her, there seems to be no ramifications for her behaviour.
