Politician campaigning say what?

Thursday nights I have class at 6, so I have a 2 hour drive after I get off work. I stopped at home to grab a few things and check my craigslist account (I'm trying to get rid of stuff!). Anyway, a local politician decided to campaign at my door during this process. He seemed nice, and he could tell that I was in a hurry.

politician: Not a good day to campaign the day before Halloween, huh? It looks like you're all ready.
me (confused): Sure, we're excited about going trick-or-treating tomorrow. Can I just take a flier? I'm getting ready to head out the door.
He hands me a flier.
me (shaking his hand): It was very nice to meet you! Have fun campaigning!
politician: Have fun at your Halloween party!
me (still confused): Thanks.

What?! He thought I was dressed up for Halloween! I was wearing this dress
and these boots
and he thought I was dressed for Halloween...as what? I wore this to school, and I have worn it to church!
Needless to say, I will not be voting for him on Tuesday!

I'm not sure why the pictures of my outfit aren't coming up, but know that it did not look like a costume! :)
