VOICI LE CV : 

Dear Sir or Madam,

I am writing to you because your advertisement in the newspaper to work in a sport shop catched my attention.

I am 15 years old and I am in the middle school, but I can work at weekends                       and the evening.

I would enjoy working in your shop because I'm very interested in all kinds

of sport, I'm sporty, I'm sociable and I love helping customers !

I have already worked in a shop and it was a good experience. I helped many                    people and I was very appreciated by my employer.

CE N'EST PAS FINI MAIS EST-CE BIEN POUR L'INSTANT ?
