Sometimes saying no can save you from a lot trouble.

What would you do if your sister wanted to have a party at your apartment? Would you be willing to leave for the weekend to let her party with her friends without you there, or would you say “no”?

This girl shares how her sister kept trying to talk her into letting her use her place for a party. She thinks this is a horrible idea, and now her sister is upset.

Check out how things got bad.

AITA for not letting my sister and her friends have my house for her bday weekend?

I (25F) live in the basement unit of my friend’s house.

It is a complete separate unit and I pay rent, however the big backyard is a shared space.

My younger sister Teresa (22F), lives at home with my parents still, which is about 20 mins from my house.

This is where it gets tricky…

It is Teresa’s bday in a couple weekends, on the long weekend, and she has asked me to give up my house from Friday to Monday so her and 12 of her friends who I’ve met maybe once can party without my parents being around.

I told her I would be fine with them staying for one night of the weekend (either Saturday to Sunday, or Sunday to Monday), but I would not want to give my place up for the full weekend.

UH OH…

She said that will not work because her friend Samantha has her bday a day after and they both want to have a full day of partying, therefore they would need to be partying Saturday and Sunday and won’t be able to leave Sunday night.

Teresa usually has her bday celebration for a weekend at our cottage however it is under renovations this year and is not available.

I have seen how the cottage looks after the weekend and it is absolutely trashed and not cleaned up whatsoever, stains and food everywhere and the floor is covered in sticky, old drinks.

She doesn’t want to give in…

My parents also never do anything to make Teresa see that’s very inconsiderate, so she continues to do it.

She has given options to me like they will all tent in the backyard and 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.

She thinks this is a bad idea.

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.

Teresa is now mad at me calling me an AH for not letting her party in my backyard and basement unit all weekend, and says now she’ll do nothing for her bday now because all cottages or campsites within a 5 hour drive are all booked up.

I said it is not my fault that her and her friends have decided to start planning a week and a half before the long weekend.

Her sister refuses to compromise.

I think my offer for one night is nice enough considering I don’t know any of her friends very well, and I know I’ll be cleaning up after them the next day.

She refuses to only party for one day and night though.

So AITA for not letting my sister use my house for the full long weekend for her bday?

GEEZ! That sounds so annoying!

She’s being very nice by being willing to compromise especially considering her sister’s friends will probably trash her place.

Let’s find out what folks on Reddit think about this one.

This user is against letting the girls stay for even one night!

This user suggests asking the girls to book a hotel instead.

Exactly! This user knows that doing something like this on a rented property is insane!

This user knows that from a landlord’s perspective, this plan sounds horrible!

Someone’s being really unreasonable here.
