I need to go to the bank.
But they're all close today?
Closed? Are you kidding? What is it? Some kind of holiday today?
Have you already forgotten what's the date today?
Oh, it's the first of April. April Fools' Day.
You forgot all about it, didn't you?
Sort of. But it has reminded me of at least one thing I need to remember.
What's that?
Tomorrow is my wife's birthday.
Better not forget that. It's pretty strange that your wife's birthday changes every year. Why is that?
My wife is Chinese. She celebrates her birthday according to the lunar calendar.
Ah, I got it.
