My worst date ever ended with the guy saying he liked me because I was (at the time, many years ago <sigh>
slim and androgynous (but not exactly boyish, and I have pictures to prove it), he could safely fantasize about being with another guy. I hear he went on to become a semi-famous comic book artist. Can't say I've ever gone looking for any of his work in all these years.
Another one invited me up and cooked dinner for me (hmmmm. romantic... but wait ... ) and had candles all over the apartment to further enhance the mood. We were just sitting down to dinner when the smoke alarms went off -- the candles had set the bathroom on fire. So much for that romantic evening, though we did eventually become good friends.
The casual acquaintance, who dropped by my place one evening with a sixpack, just to tell me that his wife broke her hip and could he come in and party with me for awhile (nope, just heading out the door myself...). The 70 year old widower who heard I liked M&Ms and invited me over for dinner: M&Ms. The guy whose wife (wife????) walked up and introduced herself to me when he and I were having an intimate dinner in a classy restaurant.
Then again I've probably been a few guys' date from hell too... Movie and a migraine? I'm there!!! A double date where the other guy's girlfriend spends the entire time inadvertently insulting my date -- she did not know his background, and managed to find just the right way to offend him, and thought I'd tipped her off in advance... An unfortunate and completely unplanned combination of allergy pills and (only!!!) two glasses of wine -- I got a ride home in a police car that night.
