My daughter was on a group chat with her friends from the middle school and someone invited their brother in who is 13, she knows this boy as she’s been to her friends house many times, he heard my 3 year old in the background playing and he said I wish he would shut up and die. I’m furious a 13 year old would say this, he’s then claimed it was a joke! Iv told my daughter she’s not going to this house anymore, their mother wasn’t home at the time she leaves them home alone when she’s at work and leaves the 13 year old to look after the younger child. I’m so annoyed. AIBU? is it just a child’s silly joke and nothing to take to heart?
