good question!
right now in my handbag i have this scrap of paper with the word "memo" written on it, which was given to me probably a few years ago now on a halloween when i went to la carafe downtown (my favorite bar still) and the bartender pouring the wine was dressed as an office guy and looked right at me and said "DID YOU GET THE MEMO?" and i said what memo and he said "THE MEMO" and then handed me the little slip of paper with "memo" written on it.
still have it. it's right here with me in the cafe. why?
in case i run into someone who says "did you get the memo" and then i can pull it out and say yes, I DO have the memo?
