I really enjoy having an original answer to a question that's mostly asked to be polite.
The adorable young man at Trader Joe's was chatting in that way that I never can tell if someone is just that friendly and good at small talk, or if they might be flirting, or if they flirt with everyone or if this is for me. But I was pleasant, remembered that the nice answer to "How's your Friday so far?" isn't "Fine," but "Pretty good, yours? When did your shift start?" (In other words "I acknowledge that you are a human and not just my cashierbot.") "Three. I'm working closing. So, any fun plans?"
And I decided to just answer, even though there was no way that my plans were exciting. "I swear I have a reason for asking this...do you watch South Park?"
"Yeah, when I get a chance, I do."
"Well, my daughter is cosplaying Kyle at Fanime and I'm making her an Ike doll."
OK, I know the next spurt of enthusiasm was genuine "That is AWESOME! Is that what's in that bag of fabric, a future Ike doll? If you had said 'I'll give you a million dollars if you can tell me what I'm doing tonight...' That's really cool! Good luck with that, have a great weekend!"
