If I met prince i would just say hi my name is..... and get into a converstation then we look at the clock and we've been talking for hours than exchange any way to contact each other and stay in touch 4evr
1. If I realized who he was, I would probably run to the nearest bathroom, scream, and then secretly take pictures of him with my phone until he realizes and tells his bodyguards to take me away. Then I would sneak back in and we would become BFFs. :D
2. If I didn't realize who he was, I would probably gossip to my friend about that "nerdy looking noob" over in the corner.
I would walk up to him and say "Hi Prince, I'm really sorry about your dad" and then I would hug him tight. Then I would start a nice conversation with him, one that was funnyy so we could both laugh together. Then I would ask him how Paris and Blanket are doing. When It was time for me to go I would ask him if he couldd sign whatever I had with me and I would say bye Prince and 吻乐队（Kiss） him on the cheek.
