Перевидите на англ яз ,,привет я пошёл гулять пока"

Hello. I am going for a walk. Goodbye.

That awful day I shall remember during my whole life. That day was very rainy and late at night I heard some noisy. I went downstairs to see what it was. When I went down, I saw David who was taking his clothes on. He told me with smile: \" Hello. I am going for a walk. Goodbye \". He said and immediately went out. Hours passed and there was no news from him. He got lost. We called the police, but it was in vain. We were worried and we were crying all the time. Suddenly, the next day  David came home and asked happily: \" What is the matter? Why are you crying?\"
