on Bad days, There's No Such thing as TMI

I should have known this would be a rough day.

I should have known the moment the cashier in Walgreens asked me, "How are you today?" when I was checking out with nothing but two large packs of Kotex.

If, first thing in the morning, I'm loading up on maxi pads, then I'm pretty sure you can guess what kind of a night I had. You don't need to ask about it. I know you know, just ring it up and let me out of here.

I wanted to say:
"Take a guess." (gesturing to the merchandise)
 or even:
"Better now." (thumbs up toward the merchandise)
but instead I said:
"Great, how are you?" (deliberately NOT looking at the merchandise)

Because cultural programming.
