math in the body
I admit, I saw this guy as I got on the bus and immediately put him in a mental category: scruffy beard, lots of tattoos... punk, right?
Then I saw what the tattoos were of and I had to change all those stupid judgments and expectations. I mean, I liked math when I was in high school but I never thought of getting any equations or graphs tattooed!
I like being surprised like that, having my expectations shattered.
