Me: Happy birthday, honey!
S: Not yet.
Me: Yes, it's your birthday today. You're four years old!
S: No, not until it's a happy birthday.
Me: Oh, you mean when we celebrate with cake?
S: Yes.
Me: Haha. It doesn't work that way. You're four years old as soon as you wake up. You're four years old now! And we will celebrate today with cake and balloons!
S: Don't sit on my balloons because you're a big man...
