It's happened to almost all of us, you sign in to your Facebook account and, for no particular reason, you notice that your friend count is less than it was last time you noticed. Someone "unfriended" you.

At first, it bothered me when I'd notice my friend number go down. I'd wonder, did I say something that offended someone? Did somebody see me on their friends list and decide that I just wasn't that important? What happened?

The more I thought about it, the more I realized, does it really matter? I've mentioned before how much I appreciate social media and the opportunity to keep in touch with old friends, distant friends, and relatives. And, for the most part, I have the most important people in my life on my Facebook already. So if you can't put your finger on who the missing person is without having to spend a lot of time searching through your friends list, and it's not someone who you interact with on a semi-regular basis, is it really that big of a deal?
