"Who long have we been married?"
"So, that's chocolate."
"Yes."
"And for the filling?"
"Do I really have to answer that?"
"So, that's chocolate."
"Yes."
"You want any fruit in there? Raspberry or -- "
"Really?"
"So, an all chocolate surprise birthday cake."
"You know me too well."
"I can't wait to surprise you."
"I can't wait to act surprised."
