Floor letters in an elevator

Sometimes, the conversations that my guy and I have can be amusing.

"You are such a bad girl," my guy tells me after I have teased him.
"But, I'm a good girl," I said in protest.
"No, you are never a good girl," he tells me, as we both walk towards the elevator.
"Yes, the elevator has the letter G, which stands for good," I reply.
"That's not what it stands for. It also has the letter B, which stands for bad. Using your lettering, put B and G together and we have you, a bad girl," he insists.
"You're being Mr Meanie again," I reply.
"There should be a letter C as a floor. You're cute."

He's sweet.
