My own kids and I were walking through the middle school the other day after school, en route to tae kwon do class.

"We're headed to tae kwon do," I told my boss and a passing colleague, smiling.

"Do you do that with them?" my boss asked asked, stopping to chat.

"Oh no," I said, chuckling. "I just sit there using the free internet."

"She grades," explained my colleague.

"Well, I wasn't sure," my boss qualified, pantomiming some punches.

"I'm just not the type of person who would succeed at tae kwon do," I said. "Can you see me, like, sparring?"

"Oh, I can totally see it," said my colleague.

"Really?" I said, wrinkling my nose. I did a side kick and asked a nearby student, "Hey, Alex, could you see me doing tae kwon do?"

She burst out laughing.

"See?" I said to my colleague.

"Oh," she said, "I didn't say I thought you'd be GOOD at it. I think it would be really funny, actually. It just seems like something you would do."
