Bonjour,
One day, something happened to me. I went to the beach and then I had the idea to go for a swim. I went to the sea and I saw a little boy drowning. I was going to rescue him and bring him back to the sand. I had called for help to provide for the saved. Without me, he could have died. Fortunately I was there.
Voilà, j'espère t'avoir aidé
