November 17 is National Unfriend Day, a fake holiday if there ever was one, but a holiday with a message we can all learn a thing or two from. As you get older, you tend to outgrow things: clothes, toys, missionary sex and, especially, people. It’s a natural part of life, but some so-called friends are more trouble than they’re worth. They’re holding you down and holding you back, and in order for you to fly free like the majestic bird of paradise you are, you might need to cut ‘em loose. Here are five types of friends you should consider unfriending this holiday season. Ah, rejection: the gift that keeps on giving.
