Ciphering a word.

Good morning~ I woke up just now wondering where my brother had gone at 6.00 in the morning only to discover that my whole family was in the living room watching the opening of the Olympics.. Hahahha. Anyway, they invited Rowan Atkinson along and he was just hilarious just now because he was acting as Mr Bean. Hehe. Sooo, I still haven't discovered who the secret admirer is. Max is still very resistant to tell me more about him but he gave me a code to solve to find out his name and the code word is "kitty". Does anyone know how to play the game called CIPHER? This is the code I have to solve: Knpeh Bmmdq - and if anyone solves it, I would appreciate it very much! :( Max keeps on telling me that the guy is too shy to talk to me but when he gets the chance, he will. "Let destiny and time do their job" is what M2 keeps telling me. *Sigh*. Oh well, since Max doesn't want to talk about him all the time, I'll drop the subject now in front of him Huhu. Although I said - Okay I won't care about him anymore~ And I won't talk to you about him~ And he was like, Okay suit yourself. But that won't happen for him. (Meaning he will keep talking about me to Max... Hoih).
