He’s gone, but there’s a nagging feeling in my head

“-ll… huh?” I look around, where did John go? He was just standing in front of me, and now he’s seemingly vanished, nowhere to be seen. Eh, whatever, he was being a little cunt as usual. I’m happy to be rid of the asshole. I check my watch, and notice the time, “Oh shit!” I hastily get ready to run off.
