I have this bad, particularly bad when I have PMT.
Hate noisy eating, gives me the rage. My dad used to eat so noisily, my sister used to get wound up about it and copy him so I had two of them at it. This was after my mum died, we were an unhappy unit and these tense mealtimes did not help.
I have a really noisy eating colleague, I would say she eats like a dog, but that would be an insult to dogs. And she constantly eats. She made so much noise eating a noodle soup (slurping, sucking in and chewing) that a young intern quite a few desks away looked around with horror when he heard her.
I also hate colleagues tapping on a keyboard, particularly the cheap ones we have at work. Some fountains cause me to feel tense. Hate the sound of water sloshing around an iron. Or the crowd clapping at golf tournaments on TV - have to leave the room if my DH is watching it.
I realise it's me, apart from the noisy eating which is just gross bad manners.I felt murderous in work yesterday because of the keyboard tapping. Even though my period was not due it indicated that it was on its way - and low and behold, it arrived!
