I … didn’t think you knew that out of personal experience. I thought you were joking, Tony!
And that doesn’t actually answer the pertinent question: was I /supposed/ to know this?
Except I did answer it. I’ve brought it up before, to you. I figured you knew. QED.
No, fine, okay.
Last year you were dying, and your birthday was presumably weird because of it, I don’t know. Since you haven’t /had/ another birthday since then, how can you know it’s ‘just another day’?
I made you a cake.
