As she told me a story, my friend said in all seriousness:
"I think the thing that kept my parents together, for as long as they were together, was their equal love of bad weather."
This unique sentence jumped out at me. I would hear this line only once in my lifetime. And it almost stood alone as a very very short story.
Now, whenever I notice these vignettes popping out of conversations, I grab them and express delight to the people who speak them.
