Why does it happen so often when Z and I are drawing next to each other at a bar, someone will always ask if we're having a drawing contest. If we were having a drawing contest, then obviously we'd be wearing our wristbands and racquetball goggles, a requisite to each and every drawing contest.
I just assumed everyone was aware of that.
If we're wearing our casual wear, then we're just having fun-
and trying to do better than our last drawing.
