Graduation season

It's graduation season also. At this time of the day, while attention
span is short and people starts going home, happy graduates with
colourful gowns walking pass my window surely draw my attention. I get
my eyes off the computer screen or the papers for a break, for as long
as coluorful graduates are within my field of view through my window
(the image plane). I sometimes move my head (change the optical
center) for a longer gaze.
I'm getting nuttily bored I guess. I better go home.
