I was walking DD home from school and a dad with 2 DS had his hand firmly around the younger DS wrist who was around 5 and was twisting it etc so badly the boy was crying. He was dragging him up the road. After a while I got up behind him and said he could possibly break his wrist if he carried on like that. Well he did carry on like that all the way up the road and told me to mind my own business. I took a photo of him because he just wouldn't let go and the poor boy was crying in pain. He never let the poor boys arm go. It was pretty horrific actually to witness.
