The thing is, I think we have this conversation EVERY YEAR

Me: Honey, do you think they'll really give you Monday off, or will you all be working?

Husband: What? Of course we'll be working on Monday.

Me: Hunh. Well, given the workload that doesn't surprise me, but it's too bad.

Husband: Huh?

Me: Well, you know, national holiday.

Husband: What?!

Me: Kid doesn't have school, I don't have work, I know it's not a holiday in Ireland but I figured they'd let you have it off here in the states.

Husband: What National Holiday is Monday?

Me: MEMORIAL DAY.

Husband: Really?

It was like he'd never heard of it before. Yes, he grew up in the U.S.
