You know when someone says something, and you don't quite understand it? But you kind of want them to think you did so they will leave more quickly?
So I had just finished helping a man. I laughed at something he said (not that funny, but, you know, I have this job where I *get* to be nice to people). He turns back and says:
"If you were any cuter, I'd go on a search for the fountain of youth!"
I made some inane comment, b/c my brain hadn't quite processed it. He steps around the corner and says to his wife in a low voice "isn't she cute?" and then off they go.
I file it away. Then later, pulling it back up, I realized what he had meant.
Even at his advanced age, I think it would take more than the entirety of such a fountain to make it work...
