Dear jack, I had a very unusual experience on sunday. At around ten o'clock in the morning,i was walking down the street when a UFO landed in front of me. You can imagine how strange it was!An alien got out and walked down center street. I followed it to see where it was going,and i was very surprised when it went into a souvenir shop.While it was looking at the souvenirs,the shop assistant called the police. Before the police arrived,the alien left the shop and then visited the museum of the flight.while the alien was inthe museum.I called the TV station.isn't that amazing! Yours, Ted
