Yeah. Tomorrow at work there's fire training going on, and when they do fire training they test the alarms when unexpected. I'm not put down to do fire training, so I just have to do my work, but I'm going to be anticipating when the alarms are going to be going off.
Nobody at work likes the noise of the smoke alarms, they all say it's loud and hurts their ears (although covering your ears seems to be socially unacceptable in this society), but I believe the difference is probably nobody else is worrying about it right now at this moment and only complains when it happens, whereas I'm worrying about it way beforehand, which makes me jump worse when it does go off.
I hated bells when I was at school. Those ugly-looking electric things that were fixed to the walls and still worked during power cuts.
It was so hard to avoid being near a bell without looking really autistic. There were two ways to avoid being too near a bell when it was due to ring; holding your hands over your ears until it rang, or isolating yourself from the rest of your friends in the hallways. Then when you told people that you were just unhappy about the bell, they did not understand at all. In fact they thought it was a joke. Kids at school were so hyperfocused on each other, that they didn't have time to worry or anticipate a bell ringing, whereas that was my worst anxiety during school life.
