Paul Ashworth: Why is it that adults aren't supposed to go mad about anything? You gotta keep a lid on it. And if you don't then people are apparently entitled to say what they like. "You haven't grown up. You're a moron. Your conversation is trivial and boorish. You can't express your emotional needs. You can't relate to your children." And you die, lonely and miserable. But you know, what the hell, every cloud has a silver lining.
