I Only Have A Select Few Friends

Good friends are hard to come by. When I was younger I didn't have any friends at all. Then I found friends that had a lot in common with me and then my friend circle expanded from there. We are like minded people who behave similarly. We are comfortable around each other. We share things, we give each other space, we don't overreach our boundaries. I will not be friends with anyone who doesn't share my interests. I am very picky.
If you don't want to be friends with someone, should you just ignore them?
Well, that's what I'm going to do.
I'm constantly telling myself, you have control over your life and the people in it. You have the choice. We are free creatures with the ability to do anything we want. Life's too short. Be careful, but be careless at the same time.
