DS1's mate was over with his mum. DS wanted to go outside to play (it was raining and friends mum didn't want to get her angel dirty) and before I could say anything she'd turned to him and said "No, you are not playing outside". Godsmacked. It's MY son and MY home, surely it's up to me to say what he can and can't do? .
(I let him go outside anyway and her DS followed shortly after - both got filthy (snort with laughter) .
