I have never had a large group of friends, instead I tend to have just a couple of friends at any one point in time. I'm perfectly fine with being alone, and tend to prefer it more often than not.
Sociall media has not made it any better. It seems that people now ask probing personal questions far sooner than what used to be considered polite, and they feel that it is their right to know. In addition, people don't seem to be able to keep their mouth shut anymore.
My Childreo, and one or two other people are about all I can stand right now in my personal life.
