A carpenter I knew used to split the grocery list with his gf when they shopped, to save time. One Friday morning she says to him, "I made decaf for your Thermos today. See if you like it."
He got home, she said how was your coffee he said he didn't notice the decaf being any different. She said "that's good. You have been drinking it all week."
Luckily, I don't have a wife to deal with
So you're the one who made the coffee that fateful morning...
@MarkiusMahamius yes, but I know what's in my coffee lol
