First of the first is first in you last of the zero is double in you first of the last is last in you who are you?

Oh, dude, you're hitting me with some riddles now! So, if I decode this, it seems like you're saying the first letter of the first Word is the last letter of "you," the last letter of "zero" is two times the first letter of "you," and the first letter of the last Word is the last letter of "you." So, if I'm the one you're asking about, I guess you're talking to me, the master of all things trivial and slightly confusing!
