When I was at my old job, about 2 years ago, some people at work friend requested me on FB. So, I obliged. After a while, I just started to delete people from my friends list. This included defriending people from my FB who I previously worked with (I was trying to cut back on the time I spend on FB). So, I defriended a woman from my old job. There was never nothing between us. I'd never date a current or former colleague anyway. Anyway, she found out I defriended her and wrote me. The following conversation:
Her: Why did you defriend me?
Her: I see you're reading my facebook messages and not responding.
Her: Why did you defriend me?
Me: Sorry, I am just getting a chance to respond now. Don't take it personally, but I am trying to cut down how much time I spend on FB, and have deleted a bunch of people. My plan was to leave on a few close relatives and that's it.
Her: But the point of facebook is to stay connected to all sorts of people, not just those who are your close friend.
Me: Hmmm, yeah, I guess you can say that is true. But I really prefer to do it like this.
Her: How will you stay in touch with people over time?
Me: There are many ways. It does not always have to be facebook.
Her: What other ways are there?
Me: You can always text or email me.
Her: I only text and email close friends or family.
Me: So, why do you care if I defriended you from facebook, if I am not a close friend or family? It doesn't seem worth it to get mad over.
Her: Because I like reading people's updates to see how they are doing and chatting through FB.
Me: Okay, but I am sorry that you feel that way.
Me: Anyway, how did you find out I defriended you?
Her: I have an app.
Me: And what does that app do?
Her: It tells me when someone has defriended me.
Me: Wow, that's very.............strange
.
Her: No, not really. I like to know who my FB friends are.
Me: Okay, well, I guess I could add you back.
Her: Thank you.
So, about 2-3 months pass by. I talk to her here and there. Nothing special. Thinking back, I was pissed for adding her back. So, I decided to tell her that I was going to deactivate and/or delete my facebook (even though I wasn't). However, I just defriended her. Guess what happened?

Her: I saw that you defriended me. Why did you defriend me again?
Me: I should have never added you back in the first place.
Her: I don't understand what is the big deal.
Me: There is no big deal. As I told you, I was just removing all sorts of people I rarely talk to, and just keeping family on.
Her: You said you were going to delete your whole FB, but you just removed me.
ME: Yes, I did. I am not too sure what you want to hear.
Her: Nothing, I just think you should leave me on.
Me: Um, okay.
I never added her back.
