I was emptying the dishwasher this morning with the cabinet door open above it, and the corner of the cabinet just drilled into the top of my head. I almost instinctively started wailing on the cabinet in retaliation. Then the anger for not being able to get the cabinet back was worse than the actual physical pain.
It reminds me of a time that I was walking through a crowded bar with my brother, and some big oaf grabbed my ass. Instinctively, I turned around and decked the person. He happened to be about the size of a linebacker, and the amount of "pain" my punch inflicted upon him was about the equivalent to the pressure of a graceful declawed cat landing on your lap, but the point was that I noticed the vile act and responded equally and oppositely.
Meanwhile, my brother, shocked, asked, "Why did you just punch that guy?" I answered, "'Cause he grabbed my ass." My brother said, "Good, I wasn't about to mess with him." While I never got around to meeting the gentleman to find out if he was just a drunken idiot or a convicted rapist, I imagine he understood my dissatisfaction.
So how do you make inanimate objects feel the same pain you feel?
