I have many acquaintances but I only have 5 people I consider true friends. These are people I've known since my late teens and we've been through thick and thin together. I separate true friends from acquaintances because acquaintances are people that you can enjoy but they are never like true friends who will drop everything at the drop of a hat to be there when you most need them.
Some people make a habit of collecting tons of people they think are friends, for some reason they think it makes them look good to know dozens and dozens of people. I'm the opposite. I sometimes prefer to enjoy my own company rather than keep up with someone that I met somewhere and hang out just for the sake of hanging out.
With my real friends they know they can call me anytime for whatever reason and I'm there for them and the same goes for me. They are always there for me no matter what. These are the friends I place a high value on. For friends I prefer quality over quantity and it works for me.
