Dates have been changed to protect the unprotectable:
My friend called to tell me she was coming to visit me with her daughter, for her daughter's birthday. I said, "Oh, what day of the month is it?, because if it's close enough to Big Sis' birthday, which is in the same month, we can have her party then, and you can be there for it!?"
My friend said," It's October 6th...."
I got so excited: "Oh that's perfect, because Big Sis' is October 8th! ..."
Silence. with a "huh" tone hanging in the air.
"Oh no...wait, that's MY birthday. Rats."
