you were walking around at lunch like you normally did when you bumped into popular rich bastard, Sirius black, he looked at you, looked you up and down and then dragged you into a corridor and sat you in a seat, he then started making you look less like yourself and more like him

"There... Your one of me and my friends now, come on, I'm not having you walk around like a loner again" he said grabbing you by the waist and walking you away.
