It’s needed on a daily basis, but I don’t ever remember my parents or any of my teachers explaining to me proper etiquette on what to do when I walk towards people passing in the opposite direction. I’ve grown up and developed my own habits but there is nothing to validate that I am right or wrong. In the street, we all pass by strangers. Sometimes we look at them and sometimes we don’t. It all depends on the situation, the vibe, and what the person looks like.
