I have a dozen friends or so that I keep in regular contact with (to varying degrees). That’s plenty for me. I’m open to new friends but I am not an active “friend collector” like some people seem to be. Some super extroverted people I know seem to use it to keep score or something. I tend to drift away from that type of person, and then hope they take the hint. My least favorite are the ones you haven’t heard from in years and then they text you out of the blue wanting to reconnect. I don’t ghost them, but I do duck out of it. They’re just bored and being a pest.
