the return of sid

nearly twenty months ago, i was visiting berkeley when i came across a squirrel i subsequently named sid.  he vanished from my life as quickly as he had scurried into it.  while minding my business, i noticed a bushy-tail zooming across a fence.  i believe it to be none other than sid the squirrel.  on espionage duty.  mission: spy on me.  for what reason?  i hope to never find out.
