<human>: Give me the gist of the text in a nutshell

I'll start. I was sitting in my room doing homework when my nose started to bleed. I stuffed a tissue up my nostril and continued working. I was wearing a hoodie, and after a few minutes of sitting on the futon the folds of my hood started giving my neck some trouble, so I just put my hood up and kept on trucking. I switched up the tissue lodged in my blood tunnel of a nose and while doing so, noticed that my pocket knife on the ground next to me was dusty. Dust is like my kryptonite, so I drop everything I'm doing, grab a can of dust remover and blast the knife. As I'm clearing the last specks from the blade, my roommate walks in and just bursts out laughing. To this day, he admits he has never seen anything more ridiculous.
