oh now i feel bad about my 'pushchair rage' comment! i only do it occasionally when people are really really annoying! But it is so frustrating how people can be so oblivious to others who need help. But like i said, i have noticed an improvement over the past few years, and when i have asked to sit down or asked someone to help me carry the pushchair up stairs, they have always been happy to do so. I think that it just doesn't occur to them, or maybe they worry that that are interfering?
anyway, i agree what other posters said that it is better to rise above it and be a good role model to my children by showing them how to help others.
