Driving a friend and her friend to go and get some lunch.
I don't know this other person well at all really, anyway she was in the back talking to me and I was having to merge onto another road so I was giving it 100% attention and didn't reply.
My friend laughed and said "x I think she's trying to concentrate"
She then pipes up "Mighty are you a nervous driver? You seem like you would be a very nervous driver"
It really pissed me off.
I think it pissed me off more because she's never driven a car in her life.
