Parking Spots and Hot Cocoa

We've all been there. We're mad at something, we're in a rush, looking for a place to park our car in a stuffed road, and then we see it... on the rear view mirror. So we quickly shift gear, start reversing in it before anyone else can steal your spot, but you're now about to bump into someone that had your same idea. Now you're ready to snap, you want to snap and start arguing on who saw it first. But what happens when the other person, simply apologoizes and backs off? What do you do with all that excess adrenaline you've built up?
