Your birthday is supposed to be a special day where your very existence and survival are celebrated by the people closest to you. Still, everyone has a very different and personal relationship with their birthday. Most adults don't pay too much attention to it; they mark their calendars and host small gatherings with close friends or get dinner with their significant other when the day comes around. Some people hate their birthday. They do everything in their power to completely ignore it and keep the date hidden from the people around them, lest they come home to a surprise party they never asked for. 

Then there are those whose favorite holiday is their very own birthday; they spend the whole year planning and coordinating birthday bashes like it's Thanksgiving or Christmas. Maybe they love the attention, or maybe the simply love a reason to party. Our protagonist's sister is much like this. Traditionally, she rents out a cottage to have her weekend-long celebration, but she didn't reserve a spot fast enough this year. That's why she's demanding to use her sister's house instead.

    won't bother me if I'm there, but they will still have to use my kitchen for food and my bathroom, and there's no way if 12 people who are 22 years old see two bedrooms they won't use the bed. Also, after 3 days of partying I'm sure people will be puking, I don't trust they will clean

    that up either in the backyard or my bathroom. It is also a shared backyard, I don't feel comfortable letting a bunch of random people in the backyard for 3 days straight when my friend, who owns the house, will most likely want to use the backyard at some point.

  • Right, Samantha simply needs a full day of partying. Beggars can't be choosers, girl! She should be grateful that her sister is willing to compromise.

    WholeAd2742 NTA First of all, it's not YOUR property to lend out, let alone the risk and liabilities of random folks drinking and tearing up the place. Sister needs to check her entitlement

    absolutely not going to want a big crowd of kids taking over their house/yard. Letting them stay, especially with no landlord permission, will likely get you evicted.

  • If our protagonist is pressured into giving into her sister's demands, she might face more pressing consequences than a grumpy 22-year-old.

    NTA. AdGreedy8386 That is a legal liability you don't want to take on. Tell them to book a hotel like normal people. Their failure to plan properly does not constitute an emergency on your part.

    for that. I notice that your parents aren't volunteering the house where she actually lives for this party, either. There's a good reason for that.

    Gossamira Exactly, OP you're absolutely not the AH. You've seen how messy they get, and you're being smart by setting boundaries. If she wants a party house, she can go rent one

    schec1 NTA, OP is renting with a SHARED backyard, having a 3 day bender for people not on the lease is a sure fire way to get OP evicted.
