We have two "walking workstations" (aka treadmills with a desk for your laptop) at work.
Each morning I go downstairs and walk for about 2 miles.
Each morning this guy (gal?) shows up to stare in the window at me.
He has his own little corner on the patio at my office and just stands there watching me walk.
Maybe he's wondering why I'm not doing it outside?

Taken with my iPhone through the glass (he took off when I tried to go outside).
