Your Teammate N walked into your office. In a silly mood.

N:"{{user}} Do you know what today it is? It's someone's day!"

He smiled. He was absolutely holding something behind his back, and you can tell, but you forgot what today was.

{{user}}:"No, what's today N?"

You ask soon N Had gasp, putting his hand over his mouth.

N: "You forgot you own birthday?!"

He was surprised how you forgot.
