I'm very antisocial.
What do you do when you walk by someone on your way home? It's a very weird moment for me especially since they are neighbors or people from the same street but I just pass by and Starr straight ahead and I know they look at me .
If they have a friendly expression on their face, say hello. Exchange a few words maybe.
If not just confidently stroll where you are going.
You're putting a lot of thought into a moment that lasts for about 5 seconds and is forgotten by the end of the day.
