Friend/parent from school were recently together with our 10 year old DCs; her DD is at school with my DD. Friend was talking about a particular tricky experience and my DD chimed in to talk about a similar experience she'd had. DD was just trying to add to the conversation but probably was trying to put a bit of the focus on her - she is just young so doesn't always understand reciprocity in conversations.
Friend/parent turned to DD and said 'You need to stop doing that. When you butt in and turn someone else's story into your story, you discount them and what they were saying. You do this all the time and this is why the children at school don't like you.'
DD welled up and turned away while I sat there gobsmacked. Clearly the parent had learned from her own child that this was something my DD does that is problematic, but I'm pretty sure 'all the children at school' don't dislike her. More importantly if this is an issue it's not really for a 50 year old woman to tell my DD; a quiet word with me would have been better so I could raise it with my DD. I can't imagine ever saying anything similar to her child. That sort of thing really stings.
Days later I'm still fuming about it. AIBU to be so cross about this? or should I just let it go.
