    This morning I found pink wallet in the canteen. Girls usual like pink, so I believed the wallet was belonged to a girl student. I opened it, try to find out whose it was. Therefore, I found nothing but 150 yuan in it. I was wondering what to do with it while suddenly my classmates Liu Yan passed by. She suggested she put up aLost and Foundnotice and I did so. I wrote down my telephone number and ask the owner to call me after seeing the notice. Later, a girl came to claim it on 3 o'clock this afternoon.
