Playing Piano at Midnight

I join a Piano Club in CGU. This week, we started to play the piano according to the time we fix up. Because the member of club overflow, I cannot but arrange the time at 11:00p.m to 12:00a.m. The piano of our club is in a room which on the second floor of the gym. There is very dark and nobody will be there at this strange time. I had heard a ghost story which tell us that don't play the music at the midnight, or you will never stop playing until you exhausted. I was very scare of going there by myself, so I called my roommate A-chou and my friend Han-Han alonging with me. Fortunately, there are some people still in second floor of the gym. Then I play the piano, A-chou play the guitar and Han-Han write the physics' homework happily at midnight. When we wanted to leave the piano room at 12:15a.m, we suddenly saw a man with pale face standing outside the windows. All of us were shocked without a word by this scene. For a while, the man said "I fix up the time 12:00a.m to 1:00a.m. It's in my turn!". Finally,We left the room quickly and no one looked back. I think I will not forget the pale face I seen, even if he is a man ,not ghost!!
