Whenever I’m at a dinner party with very clever people, I always feel like I’m the dumbest person in the room — and that’s because I am the dumbest person in the room. I should point out that I’m not really dumb dumb — well, most of the time. But by every test of intelligence I am: I have a low IQ, I failed to get into a university, I don’t understand Google maps and I don’t get how the twenty-four-hour clock works.
