A very exciting thing happened this evening after dinner. I was outside my apartment with my friend Sunny and suddenly some funny clowns came dance down the street. After they had been gone, a beautiful lady rided past on a wonderful white horse. She told us that there had a circus in town tomorrow night. Then a man came along with two tiny dog. One of the dogs had a plastic envelope in it mouth. The man told us to take the envelope. When we open it, it had two free tickets of the circus inside. We were so surprising. Tomorrow is going to be best night ever!
