I sympathize with the horny male bar patron in the late evening, having been in that position. And some of the choices available are only borderline attractive. And how in hell can you be responsible for their actions? We are not talking Gary Condit here. Of course my experience was as a single person, not married with children.
You generally dump your pick ups out by the railroad track in 5 degree temperatures with no shoes, then drive off? I just don't believe that's so.
Then again, as you said, you aren't married with children. If what another FReeper said is true, that this guy was married with 3 children, he had a whole lot to cover up.
