Today we went to climb the West Hill. Early in morning we started out and arrived an hour late.
Then we began to climb. The hill was high and some of us got tired soon, and all of us were very
excited. We cheered happily when we got the top. We had our lunch there and had enjoyed ourselves
very much. Unfortunate, when we walked down the hill, we were caught by a rain. We remained
calmly, shared umbrellas and raincoats and walked carefully. Finally we both reached the parking lot
safely. In spite of the unexpecting rain and wind, we had a good time.
