Chivalry....
I got set up for a blind date with this gal, when I was in my 20's, by a relative. The agreement was that I'd pick her up at home.
Well, she walked out the door and I was very disappointed. She was remarkably homely. It wasn't her fault, she did the best she could with what she had, but she was just not attractive at all. Whatever the opposite of "a spark" is, that was my reaction to her appearance.
I firmly kept my disappointement off my face, smiled and said hello. She got in the car and we went to dinner; as is my custom, I paid for everything. I was pleasant and polite and tried to make good conversation. Afterward we went for a walk around the mall. Apparently she was rather taken with me, as she took my hand while we were walking. I had no interest in this, but I smiled and accepted it anyway.
She was a nice girl and pleasant company and made good conversation, except that she had a grating voice that was most unpleasant to the ear. I learned that her voice was a side effect of some kind of surgery she had, to correct a birth defect that had messed up her palate and skull. She had a number of other inborn health problems as well.
It was a bit early yet when I took her home; I made some kind of excuse about being tired from work. She was reluctant to let me leave and pressured me to promise I'd call her. I finally agreed and left.
I did call her back a few days later, and told her as politely and gently as I could that we would not be seeing each other again; I declined to answer "why" as I do not like to lie but also do not wish to hurt someone's feelings needlessly.
Since "your face would make a train take a dirt road" and "I'd fear for the health and appearance of our hypothetical children if you were their mother" would both have been needlessly cruel, I declined to say anything further.
Even so, I'd agreed to take her out and show her a good time, so that is what I tried to do.
Oddly enough I still think about her sometimes. She was very sweet; I hope she eventually found a man who was able to look past her problems and accept her as she was. I am slightly ashamed to admit that I could not, but there it is.
Still, if I had spun gravel leaving the driveway the moment she stepped out the door, that would have been very unkind. Going through with the date and being as nice to her as I could was the only honorable thing to do; to do otherwise would have been selfish and cruel and a dishonor to my family.
