I wasn't in the coffee shop, but . . .

. . . it happened in a parking lot. I was getting out of my car; one space away was a man on the passenger side of his car straightening his pant leg. He looked at me and said cheerily, "I change my socks 20 times a day; I guess I'm a little weird." Uh, you betcha, I thought, but I said, "If it works for you." So I just had to Google it. I found 6.5% of Americans change their socks more than once a day. But 20 times seems a bit OCD.
