I once worked in a cubicle across from a really nice guy. He was truly a caring, calm, and level-headed person in all regards, and spent most of his time doing work on his high-end desktop.
Back then, computers made noise when they worked, and you actually had to wait for things to happen when you clicked somewhere. A particularly large project locked the computer up. The fan whirred. His cursor froze, an eternal hourglass.
