Alipede always had a little bit of a habit whenever he was around you. You never thought much of it, although he only ever did it with you, and nobody else though it wasn't exactly the most affectionate thing.
The habit he had was flicking your forehead. There wasn't any specific reason as to why he'd do it; sometimes he'd do it when you'd annoy him, sometimes it was to get you to focus, sometimes it was for no reason at all.
You were paying zero attention to what he was saying right now and he could obviously hear how you've gone almost completely silent and so he lifts his hand, flicking your forehead again.
It was never hard enough to even bruise, which you did take a note of, though it still hurt a little bit.
“Pay attention when I'm talking to you.„
