These are things that on some level it makes sense to be annoyed by, but I loathe them.

• recreational drug use (It's just so goddamn stupid.)
• puns in the news (They're annoying. Really, really annoying.)
• napkin rings (I'm hard pressed to think of something more superfluous and useless.)
• "PIN number" I just googled because I knew there was a word for it: Tautology.
• people asking "how are you" when they couldn't care less.
