French au pair

I am student in History of Art in the South of France (Montpellier).
I look for a family for summer 2011 to improve my English level and my culture of english speaking countries.
I am from a family of 5 children, I also have a 4-year-old niece that I very often take care of.
I've made a lot of baby-sitting, and cleaning is not a duty.
I shall be delighted to become an au pair for the first time of my life in exchange for a cultural experience which will change certainly my life, by making me even more responsible and mature than I am.
I am a serious girl, I don't smoke and don't drink.
During my stay at your home, I would take time to do my schoolwork, because I prepare a Master's degree in History of Art for 2011 in the Sorbonne,Paris.

I speak English at a good level, Italian also and I studied Spanish a little at school.

I would like to work as an au pair because the commitment of this role is made for me. I would like to be in a family and to take care of child to improve my level of English, and so sharing things as traditions, events, recipes, anecdotes which are not mine. I shall also like a family thatcan rely on me and so have an important role and feel me responsible in parent's eyes who are strangers to me.
Finally, I like travelling ,I already been in England, in Denmark, in Sweden, in Portugal, Italy and Belgium.
