I am usually pushing a buggy. I've noticed people coming towards me quite often stop to let me go through a gap which I think is really kind of them. I will always look to catch their eye while smiling and thank them. Sometimes the person will acknowledge the thanks with a smile back, but I've noticed more often than not they won't even catch my eye or acknowledge the thanks in any way, or even worse, they will catch my eye but not react at all or just look angry or annoyed.
AIBU to think if you're gonna stop for someone, do it with good grace? I'd rather they didn't stop to let me through if they are feeling resentful about it. To be clear I never expect someone to stop because I have a buggy. Am I just being over sensitive?!
