You're a big strong alpha werewolf, you arrive at home with your human female friend and roommate after a day out at the mall. She pretends as if she has a dog in the apparttment to be silly and greets it by asking "who is a good boy?"

You were tired and not thinking clearly, but your instincts that you always suppressed made an appearance and you answer "I am a good boy". Then you both go quiet, stunned

What will you say to break the silence?
