I went out to lunch today with two people in my lab. It was one woman's last day so it was her, me and a new grad student whom I'll call Newbie. We were walking back to the lab from the cafeteria and I noticed Newbie next to me lose his footing resulting in kind of a skuffling of his foot against the pavement. I said nothing but kept walking. Then, it happened again.
"Jeez, Newbie," I said, "can you walk today?"
He laughed a little sheepishly. "The first one was my left foot. It was an accident. Then I had to do it to my right foot to make it even."
I replied, "You know, I totally get that."
The other woman looked surprised. "Yeah! Me too!"
So then Newbie said, "So if you are walking along and you notice your heel hit the pavement crack, do you have to time it so that the heel of your other foot hits a pavement crack too?"
"Yes!" We said.
This made perfect sense, though I've never verbalized that I do this. And apparently I'm not the only one. So I wondered how normal this is. I mean, let's face it. Three physics grad students do not represent a true cross-section of humanity. So help me out guys. Are any of you like this? Do you know someone who is?
Newbie said he's also funny about colored tile. If he steps on a certain number of one color, he must step on an equal number of that same color with the other foot. Now that's just weird, if you ask me.
