outside the school is a small park with a climbing frame and a swing. There is also a tyre on some chains - the tyre is on its side IYSWIM so about four kids can sit on it, then if you push it, it swings.
The dad has this kind of thing going on where he pushes four or five children (including my dd1) who all sit on the tyre. He pushes them very hard and fast - they all love it. Its a potential nightmare as the tyre swings very wide and fast - I saw a child get clunked on the head with it once and it totally floored them - eg it is quite dangerous, also the girls cling on and could easily fall off.
Before he came along the kids used to do it themselves which was fine as they werent really big and strong enough to push it that hard. It really irritates me that he does this but I don't quite know whether to say anything. I dont really know why it irritates me either as I have pushed dd1 hard on it before. I just find it quite...presumptious.
