I think I'm a bit over-sensitive to noise, especially noisy music in restaurants and cafes etc. It makes me twitch. My husband has fallen in love with MacDonald's, so we go about once a month for him to indulge. But they play the most ghastly music at full belt, and there are always dozens of badly-behaved children galloping about shrieking. He munches through his quarterpounder thing, I just have a horrid paper cup of hot tea and grit my teeth!
