They don't go out the rest of the year and see Christmas as an excuse for something special. It doesn't mean the same thing to night people because practically every night of the year is like Christmas, really. And that is something that only night people can ever understand".SUE TILLEY, 40, Job Centre worker, former nightclub picker, model for Lucien Freud, friend and biographer of Leigh Bowery`I think you either are a night person or you aren't And I am By going out, fantastic things have happened to me It's changed my whole life I wouldn't know what I'd be doing if I didn't go out I lived in Paddington until I was six. My mum despaired when I was a child."She then leans forward on the sofa "I tell you what makes a fantastic night out - free drink Then everyone gets drunk Otherwise, there are always a few Scrooges around. So the idea would be to go out with friends, have a few drinks first, go out to a night-club, see a few minor celebrities and then get off with the man of your dreams. Yep, that's it." So how often does that happen? "Very rarely," she says "But it does now and then."Then she stops. "I went to the opening of the art show `Sensation' and I was so thrilled to see Jeremy Paxman, who I have fancied for years. I couldn't look at the art because I was too busy following him around." But is he a minor celebrity? "I think he would probably think he's a bit major He's so rude I love him. He's marvellous on University Challenge!"So what makes a night person? "You like to have fun, you want glamour You like a drink. I always find people who go out at night and don't drink very odd. How can they bear being surrounded by drunk people?" she says, adding: "Oh yes, another thing is that I don't need a lot of sleep. But she also knows how to have a good night out."I love getting dressed-up to go out and putting nice make-up on I like to get drunk before we go out I like the dark of night-clubs I love glamour, that is what I really like, I guess. And there is nothing I love more than seeing a minor celebrity. If I go to a night-club and see three minor celebrities, I will be soooo happy," she says, sipping tea underneath a Freud in her fifth-floor flat in north London. It comes from too much drink, I suppose."Too much drink is a key ingredient of Sue Tilley's idea of a good night out.
