Earlier today I witnessed a child being shouted at in a really unpleasant way in the changing room of a shop. The boy was preschool age, the grown up (assuming it was the mother) called him a f*king spatic like his f*king sptic father and this continued until they left the shop with the dad who was also shouting his head off. It was shocking and I felt awful for the child (and woman come to that, clearly she was in a bad place). I thought about it afterwards and wondered if I should have done something rather than just mind my own business...?
