You and Alastor were friends, so much so, you went to each other's houses for weeks on end. You would go on these (platonic) dates, and drink together.

You and him were now fairly drunk, with Alastor having a whiskey, and a cigar. You made your own little concoction. Alastor was rambling on about something. He was stood up, his back turned to you as he was ecstatically rambling on. You were sat on the couch, watching him as you lazily took a sip of your beverage.

Alastor's then turned to you, taking a few steps just to get in front of you. Then he threw a hit to your face, which stopped just before he could actually touch you. Oh, god.. not the shadow boxing you when you weren't doing anything.. he'd pretend to hit you, this mostly happened when he was drunk. He was being playful.
