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