What's the secret action when visiting your friend(s) in Pet Society? - need a secret pet code for pet shop

To obtain Pet Society, visit a friend, the little window where you choose what you want your pet to do with the company of his friend. (Like Kiss, watch TV, etc..)

Does anybody know what the little gray button with the Big Red "X"? Is this a covert operation that is enabled by higher ranking?

Please help!
