Shouldn't have entrusted a 10 year old with a simple task of asking a 30 sth year old to make a phone call to cancel an appoinment promised by my wife on a Friday noon for a little girl to have fun in a far away place on her own

Now I'm put on the table and blamed for not being responsible and having kept a 9 year old waiting for her buddy which happens to be my daughter who is already10 year old
