My neighbour's DD is 8, and plays regularly with my DD. Today, after she had gone home, I found that she (neighbour's DD) had scrawled 'Fucking Bich' (sic) on a bit of paper in DD's room.
I know I'm quite naive, but this has genuinely shocked me. I don't expect DD to go through her life without being exposed to bad language (even I have been known to mutter FFS under my breath and out of earshot), but I just didn't expct it in this context and at this age. DD is only 6, FFS
So, do I mention it to her mum or not???
