I think dog's barking is the worse, but maybe that's because my next door neighbor lets the barking go on too long. I also cannot stand loud, noisy crowds, or sharp beeping alarm type noises. I tried to go shopping with a friend, and the store was very crowded. I spent nearly an hour wandering around, getting distracted, even though I had bought a list. I finally gave up, purchased a few things, and left the store. Even there, people were grouped around the entrance, smoking, so that I was forced to walk through a wall of stinking smoke just to get to fresh air. People are definitely at the root of it all.
