The postcard

Benny was home alone. He had been playing PS since early morning. He was really excited about the game. When his mother came home, she gave her a mistery box. His mother doesnt say anything. Benny was really excited. The boy tried to open the box but his mother stopped him and she said: "Only open at christmas eve!". The time passed and the boy was became more excited. The time arrived to open the box and the boy teared up the box. It was a post card from his father. His father was a soldier and killed during the war. This was his last letter for Christmas.
