Sits behind us on his horn. My daughter is good on the roads cycling to school and shops so I thought I'd let her try a main road on a Sunday morning which she had asked to try the road to swimming lessons. We were on a two lane road with me outside her not much further out on the road than primary position. I rode behind and outside her not much further out than primary position. Some idiot decided to come up the inside lane and sit behind us on his horn for what seemed like ages until a gap appeared in the outside lane. I was expecting abuse as he overtook us but he kept his eyes forward and didn't even look at us. My daughter wasn't phased in the slightest and calmly asked why we were being beeped, accepting my answer of impatient. This was obvously a minor incident at worst but it's amazing the difference in how I felt (very angry) compared to not being bothered at all if I'd have been on my own.
