types I just can't understand

1. The couple who enters a movie about 15 minutes after it started. They seem to be holding like five different coats and they're making no effort to whisper as they look around for a place to sit.

2. Your friend's friend's roommate who, when you ask him at the bar if he knows so-and-so who works at his company, responds: "Oh, yeah! Tim's good people."

3. A public figure who, while giving a speech or talking on a panel, notices someone in the audience has gotten up and left the room (probably just to go to the bathroom or something!) and decides to make note of it. "Uh oh. Am I boring everyone?" he "jokes," receiving a few unenthusiastic laughs.

4. The friend (who you see maybe once a month at best) who texts you on a Friday at 7pm: "Hey, know this is totally random but I'm like a block away from your apartment right now!! You around??? Wanna hang out??"

5. The person who uploads a Facebook album of pictures from middle school, titled "Look what I found!!!!!" or "MEMORIES :) :) :)"
