I discovered that my roommate was using my laptop after I noticed that it wasn't exactly as I left it nearly every time I would go to use it. It would be in a different place on the table, all the windows would be minimized, and the web browser would be on DuckDuckGo which I never use.
He would always deny using it and accuse me of forgetting about where and how I would leave it after I was done. I wanted to, no I needed to get to the bottom of this mystery, so I decided to investigate. I had no idea what I would find, but I am shocked and so fucking happy to have caught him red handed with my laptop open, in front of him in a place other than where I left it. I can't wait to show him the proof that he has been using my laptop and lying about it the entire time.
