     Last year, our class had a terrible experience. One week, we decided to go on a picnic to Ao Vua. Soon after we arrived at Ao Vua, it started to rain heavily. We had to wait for three hours on the bus until the rain stopped. We got out of the bus to have lunch because all of us were very hungry. After lunch we went for a walk and one hour later we began to go swimming. Unfertunately, it began to rain again. Everybody got wet when we could come back to the bus. We left Ao Vua without swimming.
