I was on the train yesterday with the DC & there was a mum with her 2 boys sitting opposite, the boys were aged about 6 & 9 at a guess.
The youngest lad was playing on what I think was a PSP & started to get frustrated, he was moaning that he couldn't get past this certain bit then in a temper shouted & threw the PSP in the floor (really hard too) folding his arms & sulking. I was but his mum scooped up the PSP, wrapped her arms around her DS & said 'don't worry babe Mummy will help you get past that bit' to which he tried to shove her off still moaning so she fished around in her bag & handed him a chocolate bar
AIBU to be miffed by her reaction? If DD had done that I would have taken the PSP (or whatever) away until she said sorry & learnt to treat her things with respect.
