Just because you are friends with someone you don’t have to talk to them. I have like 400 friends. Very little interaction with any of them. Sometimes I get friend requests from people I don’t even know but Facebook says we have like 50 mutual friends or more. Sometimes I delete the request and other times I accept it. Depends what group of friends we have in common. If it’s a military friend I usually accept it. But if it’s high school friends or something I will delete it.
I have a bunch of people I barely knew friend me. I accepted and spoke with them a bit, Nothing bad came about because of it.
That’s how it started with me, one friend from school friended me, which led to another, and another and it snowballed. I’m now up to 60 friends.
Just decline the friend requests you don’t want, you don’t have to say anything to them, they’ll probably get the point. If they harass you then you can block them. I’ve never had to block anyone, I don’t even know how.
I hardly ever look at my Fecesbook. I have tons of “friends” but I consider them more as sources. I only friend somebody who does something interesting, art or music primarily, and occasionally people who hang around those types of things with an obsessiveness I can’t be bothered with. So every once in a while I’ll get a text “so and so sent you a …” and maybe I’ll look at it.
