I know what you mean; I cringe every time I see one. Once a pheasant hopped off the pavement in front of me, but instead of running across the road like they usually do, he just ran up the edge of the kerb for ages and ages. I was scared to go past him because he would doubtless have decided that was a good time to cross the road, but it ws so funny to watch his little legs running like mad. I wasn't holding anybody up, btw, there was only me on the road, thank God, or I would have had to risk trying to go past him and the inevitable outcome.
