I have a friend who shares a "deep thought" of the day as a Facebook status update, which I never really understand. Guess I'm too shallow. Then there's another friend who drops tidbits about his travels across the country—he's a flight attendant—while leaving out all the good parts, like the name of the celebrity who just behaved badly on a flight. Should I unfriend these people? I can't in good conscience, because in these cases, they're actually my friends, not my "friends." Jimmy Kimmel recently told fans during his late-night show to "pull some weeds" on Nov. 17 for National UnFriend Day. He made some valid points and even enlisted William Shatner in the cause. Sure, I know there's some fat in those 395 "friends," but I can't let any of them go. Could you? And how will you explain to your cubicle mate/brother-in-law/fourth-grade pal that you're no longer friends?
