Long story short: We hosted my daughter's birthday Friday evening. One of the moms got lost finding our home and when I got on the phone to help her find her way, she berated me and called me names (calling me crazy, stupid, etc) - she was roaming around in another part of town where I do not live so I was unable to help her without pulling up a map - hence why I was "stupid". Upon arrival, she grabbed her daughter and another girl and took off.
I did not realize she was stumbling when she arrived but another adult pointed it out after she departed. I was still reeling from the phone call and wasn't quite processing what was happening. I am feeling very guilty that I let her drive girls home but was able to confirm that everyone got home in one piece.
I have pieced together other things I have noticed and I think she is an alcoholic (smell of beer at noon at school, etc.). She has also yelled at kids when volunteering in the classroom - this is hearsay from the kids.
I am so uncomfortable post this interaction that I want to avoid their family. I do not think trying to talk to her would yield anything beneficial. Here is my dilemma: Do I inform the mothers of the other kids who often ride or hang with her daughter? How do I make sure we include her daughter ongoing after this interaction? I do not want to impact the reputation of the child but would be so angry if my child ever got hurt and someone knew about the situation. Do I have a duty to do anything about this?
