I wanted to take a closer photo of the squirrel and chased after him for almost an hour simply because I was not prepared with a telephoto lens at the time. After almost an hour of escaping he stuck out his head from hide and was suprised to see me still there chasing after him. The look of surprise is very impressive as if to say "Not yet?" I think I couldn't have taken this instant shot of his look of surprise if I had tried with telephoto lense at that time.
