Many years ago i saw a cyclist giving a lad a good slap as i passed by. I thought about intervening but the cyclist after doing the deed caught me up on a hill. Naturally i feared for my safety so i thought i'd humour him and ask what he did that for? He told me that the lad had thrown a broom handle at his front wheel trying to get the stick between his spokes to bring him off his bike.He said he was doing about 25 mph and if the bike had stopped suddenly he'd have been badly injured,so he went back and caught the git to teach him a lesson. I think he did the right thing!
