Light Years Away

Have you ever been in a conversation and you weren't even sure you were all speaking the same language? Tonight I was in the middle of conversation like that. Adrian and Adam were discussing sound waves, light particles, and the like, and one would say something and the other one would know what he was talking about and say something like, "Yes, and then there's....." and the other one would go, "Right, and have you thought about...." and so on and so forth. Who else but Adam and Adrian would know such details?! Well, they were certainly on the same wave length, but I was light years away!
