Today Harry James Potter is 37 years old.
He’s lived two decades more than the age he was when he willingly died.
So he refuses to eat his birthday cake unless Ginny admits he’s 20 years old.
What do you mean I’m almost 40? No. I died at 17 and was reborn. Technically. I’m twenty. I’m practically a young boy. Don’t “Dad” me. I’m twenty years old. Ron, tell them.
