Meh. Here's a better one, that I don't feel guilty about at all:
I was doing a tempo run a few months ago. I was on the sidewalk and came up on this couple talking to a guy I believe was a realtor. (There was a for sale sign on the yard, and he was dressed for the part.) They're facing away from me.
Realtor guy is gesticulating and really into whatever he was saying. I shout "passing on your left." The non-realtor guy pulls his wife(?) to the right. The realtor doesn't respond, just keeps blabbing.
I had nowhere to go--little fence in front of the house and trees to the left. There is a tiny space and I decide to sneak thrpugh but just to be safe I shout again. "ON YOUR LEFT!"
Realtor turns around--to his left. Right into me. My fists reflexively go up, I hit him hard in the chest. He goes down. I jump over, keep running, and say nothing.
My wife, upon hearing the story, told me I'm a complete assh0le for first trying to sneak by and then not stopping after I floored the realtor. I think I taught him a valuable lesson. Thoughts?
