Graduation Photo Taking

this is what he said, when we celebrated yw's birthday.
"This is a girl's cake. I don't wanna eat girl's cake."
But he still finished the cake after then.

Today we have graduation photo taking.
He said, "we are wearing dress, girl's dress."
I supposed, "you are wearing the graduation gown! (and maybe it's once in your lifetime wearing the graduation gown.)"

I teased him, "yesterday you said not to eat yw's birthday cake, but u did. That's what happen now: You've become a girl now, and wearing on girl's dress!"
