Several of my friends recently dropped checks in the mail for me. Sending checks is a bit antiquated in the age of PayPal, but it was a much easier system for managing this particular endeavor. Plus, I thought, I should get a kick out of the random notes and detritus my friends stick in the packages they mail to me. I wasn't sure what to expect, but when they arrived, to a man, every single one of them sent nothing but the check in an otherwise blank envelope. These are some of the most creative minds I know, so I was surprised when nothing odd rolled in. Though two of them did write "sex" in the memo area of the check. (And, to be very clear, the check was not for anything remotely sex-related.) I at least thought one of them would send one of those huge checks you get for winning a golf tournament.
