They say, by the time you reach an elderly age, you'll be able to count your true friends on one hand.
I have acquaintances, I have people I can call when I need to talk, but having grown up, the way I grew up, I do tend to be more of a 'private' type of person. IRL.
There are those in this world, that enjoy a little solitude, and then there are those that enjoy to be around many people. I prefer, smaller, social gatherings.
I don't find you, as outside the normal realm of how people are.
