I just entered a round a bout and could have caused a collision. If it weren't for the fact that it is raining and the round a bout is just tiny, meaning the other car was going pretty slow - he would have hit me.Yes, it was my fault - he was on my right and I should have given way.

It made me think of this thread.

Naturally, after I braked, I looked at him and was very apologetic and said "I'm really sorry" (though our windows were wound up, so he wouldn't have heard - but would have seen iykwim.)

I was expecting abuse - he smiled and waved (in a nice way - I didn't get the impression he was being sarcastic iykwim) and said "it's ok love - no harm done". (yes, I can lip read).
