I just went to the bathroom, and there was this little fly that wouldn't leave me alone. So when it landed on the mirror, I squished it with a piece of toilet paper. Usually I just throw the paper out without thinking about it, but I decided to look at the bug. And there were two red spots surrounding its body. The bug bleeds red. I squished it, killed it and made it bleed. Poor little guy was just living and I killed him because he was annoying. I feel really bad right now. :(
