Is AUTHOR wrong in the post ? POST : My sister had his friend a while ago who used to always get into trouble. The friend was banned from so many peoples houses so that was my first red flag. We didn't blame her for the stuff she did because her parents didn't take care of her and she didn't have a positive role model. She then got expelled from school which was my second red flag. I really didn't want to her in my families house but my sister liked her so I went with it. Fast forward a few weeks and it is my sister's birthday. My sister invites this person over and the person ends up stealing my sister's birthday money. We know it was her because no one else was in the house was the time.

We kick her out of the house and talk to her mom. Her mom denies the fact that the girl stole from us and we never got our money back. We could have called the police but we didn't. Fast forward to this girls birthday and no one in our family wishes her a happy birthday. Her mom then contacts us saying that her daughter was really sad we didn't say happy birthday. I don't see why she thought she would get a happy birthday after stealing from us and getting kicked out of our house.

So tell me AITA for not saying anything to her for her birthday
