Okay so, I think that this is most likely just introverts. I feel like the only other explanation is that you don’t like the people you know, and in that case you should reevaluate your life. Sorry, not sorry. The people you know should be good people and bring positive impact to your life, otherwise what’s the point of knowing them? Obviously you can’t just cut out every single person that negative at once or easily, but that would probably make you enjoy seeing people you know in public! or just at all.
Yeah, you’re probably an extrovert like me. There’s also a good chance that you like most of the people you know and they like you.
