I would be like "Oh my gosh!" And then I would think "How is this posible?" And then she might say "Um, me and my friend got lost, we need some help" And then I would ask "What's your name?" ('cause it'd be really weird if 你 new the person at the door when they don't know 你 back) And then she'd say "I'm Cream, and this is my friend Cheese." And then I would say "Well why don't 你 come in till we can find a way to get 你 back home" And then I'd help her and Cheese find there way back to Mobius some how :)
