Ego
Sometimes, only sometimes, don't you wish that all the writers, bloggers, musicians, letter-writers, columnists, pundits, poets, actors, singers, journalists, film makers (and that guy standing on his box in Hyde Park) would put their freedom of expression where the sun never shines and shut up for a day, a week, a month? Would the world be too boring? Would people die if they didn't feel they were being creative for a few days? Would the silence be so unbearable?
