You don't have to be attractive to work on TV. If you watch any TV drama, you'll see normal people in the background, behind the main actors. TV or film directors don't want every scene to be full of Gejrge Clooneys or Keira Knightleys. They want things to look real,with normal people. That's my job. Some people call us 'background artist', but we're usually called 'extras'. Extras often have to be in the studio for long hours, but you usually only work for about two hours a day. So you should take a good book of a crossword because most of the time you're just sitting waiting.And if you're working with gfamous actors, you mustn't ask them for an autograph.They just want to do their job in peace.

When i tell people what my job is they all think i'm lucky. I suppose i am. I lest computer games, so basically i spend hours and hours playing them, to see if they're good or not. Sometimes we have to keep playing the hame until it breaks. It can be fun but it can also get really boring, playing the same game again and again. We often have to work very fast too. What I really WANT TO DO ONE DAY IS TO DESIGN A COMPUTER GAME. i studied to be a computer programmer so i know about the technical side. But you have to be very creative to design a game that's original.

I'm a house sitter. You probably think that i just sit at home all day. Well, you're right. Except not at my own home. A house sitter is someone who looks after another person's house when they go away. Sometimes i stay for just a couple of weeks when someone goes away on holiday. But sometimes i have to stay for six months, when a family goes to live for a long time in another country for example. People say that i'm a 'living burglar alarm'. That's more or less true. It's an easy job,but you shouldn't do it if you love staying at home ... your own home, that is
