Must be teaching, huh?

I live in an apartment on campus which is really convenient because it's right next to everything. It can also be quite inconvenient because… it's right next to everything. Tonight I was driving home after Yom Kippur services and the break-the-fast at temple. About a quarter mile from my apartment, my university's football team had just lost to one of our biggest rivals. I encountered road blocks and heavy traffic but eventually was able to park where I usually do across the street from my apartment building.

I got out of my car and prepared to cross the street, noting how odd I must look dressed for temple when everyone else was headed home from a football game. As I walked on the sidewalk beside barely moving traffic, a guy in the backseat of a car, potentially very intoxicated, starting yelling at me.

"Hi!" he called. "Hi!" I responded, waving politely. He yelled out our university's mascot and I again waved. He then started shouting random questions which I decided to ignore. A few moments into this interrogation, he called out, "What's your major?!" As I started climbing the stairs to the front gate of my apartment building, still ignoring the guy, I heard him say, "Must be teaching, huh?!"

I didn't look back but smiled to myself. Random guess or do I really look like a teacher? Maybe it was the outfit...
