Feeding and petting a friendly black squirrel

I encountered this squirrel on a residential jobsite in Ottawa, Ontario. Since day one on the job Mr. Squirrel was very curious and friendly; by day three on the job he was sharing lunch with me. I dont recommend petting wild squirells but this guy was so friendly i couldnt resist. I can only assume the homeowners spent MUCH time building trust with this squirrel. I have never seen anything like it in my life. An amazing experience.
