Dear Brown,
Last summer I take a part-time job in the International Camp for children. I have been told one more worker will be needed this year and I think you are fit to it. How about join us? The camp is at the foot of a small hill close to a river. It is so a beautiful place!  We can hear birds singing happy all around. Everybody sleeps in tents, that is very exciting. You usually work only five hours a day, so we will have plenty of spare time visit the area and have a fun. I am sure it will be a unforgettable experience. If you show much interests in it, reply to me soon.
