I am generally a pleasant, friendly, polite person who is very aware of other people's thoughts and feelings. I never go out of my way to do somebody wrong. I never have. But when someone is a complete asshat and cause me aggravation or worse....well, they got it coming.
Once long, long ago I was dating a young lady who's bisexual friend was quite pissed about our relationship. One day while we were swimming at the park, I came back to my '83 Camaro and found gouged into the driver's side door with a screwdriver "I suck n**ger dick." Yep. I knew it was her and I had even seen her pull into the lot. Her payback was fun. I found her vehicle parked at night and proceeded to put acid glass etcher paste all over her windshield, leaving only a small hole to look through. Yeah, I had to repaint my door but she had to get a new windshield. Even Steven.
