So, I'm stopped at a traffic light this morning, impatiently awaiting the green signal 'cause I'm already 30 minutes late to work. I look up to the utility line running over the road and, I see two squirrels running on the line toward each other. When they are about two feet away from each other, they stop and stare at each other (frantically twitching their tails).

Although I can't hear them, I know they must be barking up a storm at one another. I'm thinking, surely one or even both of them are going to turn around or back up. Do they realize there is no way they can get past each other without falling?

Then, they both started moving towards each other. Holy crap! Collision! But wait, no, just as their noses are mere inches away from each other, one of them ducks its head and the other one jumps over (a la leap frog).

What the hell?! How did they know what to do? How could they be certain that they both wouldn't be jumping? There was no hesitation in either one's movement. Is there some sort of squirrel instinct when squirrels meet at dire straits? Squirrels coming from the south-east instinctively duck while squirrels coming from the north-west jump. You know what I'm thinking...all that barking is actually Squirrel-ese.
