My daughter had a recent play date at a friend's house and I just found out from my daughter that her friend's mother left my daughter and her friend home alone for nearly an hour during the play date. During this hour, the mother completed a round trip to a nearby town about 25 minutes away by car. My daughter and her friend have both just turned 10 years old.
I am quite shocked and horrified that the friend's mother, whom I know quite well, did this without asking me first. I do not feel it was not her place to decide whether my daughter could be left home alone with her 10-year old friend for almost an hour. I'm interested to know other people's views here, and thoughts on what I should do next. I feel I should let this other mother know that I do not feel her actions were acceptable.
