November 17 each year is National Unfriend Day, as declared by no less an authority than Jimmy Kimmel, in 2010. It’s not a day to lose friends, it’s a day to sever virtual connections with “friends” on social media who—see if you can follow this logic—are not actually your friends. I think most of us have friends on Facebook, in particular, who aren’t actual friends and who we don’t even know, let alone like. Same way most of us have “connections” on LinkedIn we’ve never heard of. Well, today’s an excellent day to purge your lists—not to be mean, but to be honest and realistic. You can do it. I have confidence in you. And I’m sure you won’t take it personally if (when) I unfriend you, too!
