Seriously? SERIOUSLY?

Actual conversation I had at some point last week at work:

JC: Don't take this the wrong way, but do you smoke weed?
Amelia: Nope. Other than an unfortunate second hand smoke incident on the bus in high school I've never been high. And never will be high.
JC: Huh...you look like the kind of person who does it a lot.
Amelia (looking down): Um...I'm wearing a cardigan? Maybe you've got "High" and "Fan of Mister Roger's" confused.

and then later:

JJ: I bet you get really wild when you let loose!
Amelia: Once, again, I'm. Wearing. A. Cardigan.


What is UP p-ville?
