Am I that scary?

I will admit to the fact that I have been known to try and succeed at
intimidating co-workers before, but I’ve moved on from that place in my
life.  With my new job I get to ride the commuter bus for about 40
minutes each direction.  I’ve only been doing this for the last 5
days, but only on the first day did anyone sit next to me.  Now
the busses aren’t standing room only, but I’m starting to think that it
may be that I just look pissy first thing in the morning.  I know
I feel pissy at that time of the day.  It’s odd, but I will
continue to enjoy the extra leg and elbow room.
