During dismissal time, a friend was on a website that had the Windows XP startup sound, which was really loud. I heard it a few times, and two classmates that I was imagining things.
My friend actually asked me to put on headphones, and I asked him "Are you going to ear-assault [the word I use instead of the word people usually use] me?" He said no, but I walked back to my desk. He asked another classmate, who was really surprised when he heard the extremely loud Windows startup sound. My friend got in trouble.
