Sina: Good morning.
Cass: Bad morning.
Cass: I really meant good morning, but I said bad morning. I said the opposite of what I actually meant.
Cass: It’s Opposite Day.
Sina: Hmmmm of course! So..wait…then it’s not opposite day.
Cass: Exactly. *wink*
Sina: Wait wait wait. So is it opposite day?
Cass: No it’s not opposite day, and that’s not *wink* the opposite of what I mean.
Sina: Riiiight. *wink*
Sina: I’m confused.
Cass: Listen idiot: it is opposite day…and so that’s why I’m saying that it’s not opposite day.
Sina: So it is opposite day.
Sina: Are you sure?
Sina: Sooooooo [pause] you’re not sure.
Opposite Day should be defined well in advance of the calendar date, so that nobody questions it the day of. I propose February 29, when it exists.
