My daughter, Jane, never dreamed of receiving a letter from a girl of her own age in Holland.
Last year, we were travelling across the Channel and Jane put a piece of paper with her name and address on it into a bottle.
She threw the bottle into the sea.
She never thought of it again, but ten months later, she received a letter from a girl in Holland.
Both girls write to each other regularly now.
However, they have decided to use the post office.
Letters will cost a little more, but they will certainly travel faster.
