DD went to London on train to attend an event with some people I dont know/have never met. She doesnt know them very well either. She is 20. I have very few house rules/expectations from her but one that is very important for me and agreed as a family is to have the courtesy to let someone know if anyone is not coming home so we are not worrying. She bloody knows this. I have sent her a text and just tried to call but getting no response. She has done this before and swore blind she wouldn't do it again. Even I let my DH know if I am going to stay at a friends and ditto him. I get she is an adult but while she lives here under my roof she knows it is a basic expectation. She can do want the hell she wants when she leaves home. I am so fucking mad at her right now. Am I asking to much of her? I genuinely dont know anymore.
