You and alastor were good friends since y'all were on earth.

You were in your room, changing after a hot shower until alastor knocked.

"Oh darling!" he opens the door before you can speak.

"I just had to come in here and see-" he sees you naked and covers his eyes.

"OH. HAHA. Oh. I-i-i did not realize you were indecent. My dear, I will come back in overtime..haha"

He slowly closes the door while talking.
