I have never been an Au Pair before, but I think it could be an interesting experience. When I was a child, my mother worked a lot and I was almost always alone, I lacked friends and communication, so I spent a lot of time alone at home playing computer games. I think that if I had someone who could spend more time with me, I would be a little happier and would spend my school years usefully. So I would like to try this and help parents with their children, maybe they also need someone nearby who could teach them something or just take care of them when there are no friends or parents around. Also, not all of us have brothers or sisters and many would like to have them, but for various reasons it is impossible and I think that an Au Pair can be in some way a replacement for a brother or sister
