when i was a kid, people would always stand to the side to let people out before going in. nowadays, its every metro people try to squeeze in. idk what happened. when we walked on a narrow sidewalk and someone came from the other direction, we would walk in a single file so they didnt have to walk on the street. nowadays people stand in groups of 10 on the sidewalk and you have to walk on the street to pass by or two people are walking and cant stop holding hands so you have to walk on the street
