But there's more, and I agree with all of it.  That being said, I'm also guilty.

If we're so annoyed by people staring at their phones, why do we all do it?

The rest of the top five most annoying things are: talking loudly . . . not turning off the ringer . . . doing face-to-face conversation . . . and using your phone while you're driving.
