I consider it to be a sign of good luck when…
one side of the oreo is inside out
someone falls asleep on the couch at work
I sneeze twice in a row
what odd things make you feel lucky?
Not getting caught falling asleep on the couch at work. 
I work on the 10th (top) floor. When I get on the elevator and nobody comes on to push any buttons for lower floors, so I can go straight to 10, nonstop, that’s luck. People who go to lower floors are my inferiors.
