On Saturday night, when I felt like going to bed, I turned my computer off. Yes, I turned it OFF, not standby or anything else. I closed down Firefox, which had two tabs open, and a couple of other things that I had open (an Xfire conversation and Diablo II running in a window).
Woke up Sunday morning and went straight down to my friend's bar to start working and slept over at his house. Today I got up and worked at the bar for a few hours, but I just got home and for some reason my PC was turned on, with the exact same things open that I had closed on Saturday. Obviously I wasn't actually in a game of Diablo II any more, but I was viewing the list of open ones.
My dad leaves the house at 6am, and my mum leaves at 10am. She didn't see that it was turned on, which means my dad can't have done it. Is there any explanation for this, lol?
