Have you ever been accused of character dissonance?

I was out with a group of friends once when this exchange occurred:

Me: Dude, that’s whack.
A Friend (whips around): Did you just say “dude”?
Me: Um, yeah. Why?
A Friend: You’ve never said dude before.
Me: I say it all the time.
A Friend: I just didn’t think you were someone who would say dude.

It’s admittedly a silly observation, but I’ve been thinking about it. There are people out there who box others. There’s a type of person who earns good grades. There’s a type of person who will go skydiving. There’s a type of person who will get a tattoo on a whim. There’s a type of person who owns twenty cats. And if you don’t fit the box they’ve neatly labeled, it is absolutely jarring.

What’s strange to me, is the process of taking a person you have met and putting them in a box while making a checklist of information you acquire. Let’s see… a reader, check. Studying to teach, check. Engaged? Check. Disney-loving, gigglebox, soft-spoken? Check, check, check. Medieval knife collection… wait, what?! She doesn’t seem the type.

Has anyone questioned some part of who you are because they did not think it fit you?
