I was walking home from the shop, ahead of me were a man and a young child (maybe around 4 years old). The man was telling the child off. He wasn't shouting or making inappropriate threats and there was no indication that he was going to hit the child - but what he was saying was awful.
It was a lot of' your grandmother thinks you're the most horrible child she's ever seen, why are you so badly behaved, no one likes you. They won't have you in their house any more because you're so horrible.' On and on and on, and the child was crying.
I know, technically, that isn't 'abuse' and I can't imagine I'd get any kind of useful response if I reported it (also, no idea who they are or where they live) - but what would the rest of you have done? Anything?
