You must be an extrovert. I don't think it's black and white. It's more like a spectrum. Some people become more drained than others when hanging around other people. Also, some people like to hang out with many different people each day while others prefer to see more or less the same person every day. I'm an introvert, I have very few friends but very good friends. I find most relationships to be too superficial to my liking. What's the point of having a friend if you know that this friend is capable of betraying you to gain a tiny advantage? I'm a pretty good judge of people and I find that at least 90% of people are far too selfish (not altruistic enough) to make good friends. It's too draining to hang around the majority of people because I don't like them and pretending to is exhausting and frankly I don't see the point. I can only be friends with people who are as altruistic as I am (or close to it)... Why would you want to spend time with people who are constantly trying to take something from you? That's the definition of a parasite. My theory is that people with low altruism are themselves more likely to tolerate other people with low altruism. They might even prefer them since they feel more familiar. That may be part of the reason why psychopaths end up grouping together; aside from their shared thirst for power.
