You know you're an introvert when

I'm overhearing a conversation over the cubicle wall:

"I had a cousin who had some kind of radiation therapy, and she couldn't be in the same room with people for like a week. She couldn't even be with her kids. She had to go stay in a hotel."

And as my coworker exclaims, "That would be so hard!" I'm thinking, "If it weren't for the radiation sickness, that would be so nice!"
