The atmosphere Zidane was raised in should guarantee anyone that he's well prepared for sharing rooms, along with beds or small cramped tents with loud snoring knights... He arrives late finding his new roommate already nestled--AHH! What if he's already claimed the better bed? You gotta be on top of these things if you're going to share rooms...

"Hey, guessing you're my new roommate." throwing his hands behind his head, so much for polite introductions... There was always someone reminding Zidane how improper he was. Maybe he struck lucky and didn't get landed with a stiff.
