I ate lunch and headed back toward work.
I realized I didn't have my keys.
Oops.
After checking at Quizno's, the little grocery, the front desk of the dorm, at the front desk in the Office of Research, and with the campus cops, I headed back toward my building with a heavy heart.
Then I realized I'd missed one place -- the little deli on the corner. And someone had, in fact, turned in my keys there.
Whew.
