Have you gotten into a rut with your close friends? Do you tend to just watch sports together, go to the same hang-outs, or re-tell the same high school or college stories? If you want your friendships to last, you'll have to master some more difficult relational skills. Such as refusing to talk about people not in the room as well as practicing vulnerability, unselfishness, and reconciliation. It isn't hard, but it does take intention.
