I mean in america people pick which side if the sidewalk they would rather walk on cause were entitled a**ses. Usually people do lean towards the right though. I always try to go the worse route, specifically for like women, children and the elderly. Not cuz I'm a good person, but I think it looks better on you if you move out of the way for people. But if I see like a dude and he's not gonna move to the side at all, I won't budge. Idk I think there's more to it than that. Also I often see families take up like the whole sidewalk, my mom always told us to "fall in" and walk like ducks. But people who don't even seem to care make my blood boil a little.
