Recently my wife and I were in her car, sitting at a red light. From the passenger seat I glanced over and noticed a squirrel start to scamper up on a tree in the yard of the house on the corner. I remarked aloud to her,
in an imitation of Dug the dog from Up, saying in that voice "Squirrel!" The windows in the car were rolled up, and the tree was probably around 20 feet away so I couldn't imagine the creature heard me, but almost on cue the squirrel froze, only a couple feet up the trunk, grasping the bark and defying gravity. Although its body was vertical, its head turned and looked straight at us. It stayed there, motionless, not breaking its gaze upon us. However, I doubted we were the actual focus of its attention and there must be something else behind us that was holding its interest.
After several seconds of this ostensible eye-contact I raised my hand and waved at it jokingly, saying in a low voice "Hi squirrel," figuring this would be ignored and dispel the notion it was, in fact, looking at us. My wife admonished me immediately not to taunt the animal, but I didn't think my action was threatening even if it did see gesture.
The squirrel broke its pose and ran down the tree and into the street at the car, stopping about six feet away.
