    "content": "Dear Samuel,\n\nMy name is Amélie. I live in Lyon and I make the sound for plays, so my week is full of doors that creak on purpose. I am learning English since three years, on Sundays, with a dictionary and too much tea. Please correct me. I will do the same for your French, gently.\n\nCher Samuel,\n\nLa même chose en français, pour que tu puisses t’entraîner : je m’appelle Amélie, j’habite à Lyon et je suis créatrice sonore pour le théâtre. Toutes les portes qui grincent, c’est moi. Et toi, qu’est-ce que tu fais le dimanche soir ?\n\nÀ dimanche prochain,\nAmélie"
