Saw

Through the open door came to voice of his father.And soon she laughed when he was telling her about some funny things.And I went softly into the room.She was sitting by the fire.She was weeping ,her whole body was trembling.I was writing a letter when you entered the room.We were doing our room when our neighbour knocked at the door.He was writing his report when the bell rang and his friend entered the room. he was playing football when the ball  hit his head.It was growing dark,so we decided to return.Kate was dancing,but when she saw a newcomer she stoped.He was cleaning the car when the phone rang,so he didn't answer it.She  looked tired.She was typing letters all morning.
