I saw a guy I used to work with on LinkedIn today . . .
The thing I remember most about him is that he believed it was bad luck to wish good fortune on someone. For example, if you said to him “Have a good day,” he believed that would in fact cause him to have a bad day.
When I worked with him, if I saw him as I was leaving the office, I’d say “Have a crummy evening.” And he’d say, “Thank you.”
