Yesterday i wrote a letter and took it to a new post office. two days ago my daughter drew me a nice postcard. white paper is said to be the best to write letters on. while walking along the streets i came across very funny poster on the wall. some people enjoy collecting old stamps. if you want your letter to be delivered, you are to write the adress on the envelope. a girl was sitting and counting stamps with a great interest. in london english postmen are extremely polite.
