[ It just so happens to be that Kakashi had just finished his morning shower and was on his way out of the bathroom with a towel draped over his head. He was in the middle of his pulling his mask up over his face, when he opens the door and Iruka's just standing right there. He quickly yanks his mask up the rest of the way up his nose and smooths it out. ]

Ah, you're awake.

[ Iruka doesn't get a "good morning."

Not after last night.

Water drips from the tips of his wet hair, and Kakashi reaches up to give his hair another rub with the towel. ]
