I joined a Facebook group for people in my high school's graduating class. There were supposed to be about 500 of us graduating, but I think only something like 380 actually made it. Apparently walking with the class wasn't a prerequisite to join the group because I have no idea who any of these people are. I've stopped accepting their requests to be my friends. At first I let them all join my little friend group even though I had no idea who they were. It seemed like the right thing to do since denying someone friendship on Facebook is about the laziest way you could ever snub someone--even someone you're pretty sure you've never met. But now I'm not accepting these people I don't know anymore. They clog my Newsfeed with pictures of their wedding rings, babies, and news of becoming fans of "The X-Files." Their time is up.
