And you know, I kind of understand that.
If you stop and think about it, you've met a LOT of people in your life. "Met" might be a loose term, here, but think of the daily interactions, the casual strangers, the friends.
That's a lot of people. Some were good interactions, some not so good. I have a general rule: I assume good unless I'm proved wrong. It makes life a lot easier. Others I know seem to assume the bad, and they just give off a very negative vibe.
The way I see it is this: it ain't personal. If somebody doesn't get along with me, that's fine. There are a lot of other people in the world. I can't get along with everybody. So it goes.
I've already met a lot of people. A few less is okay with me.
