Dear Tom,

Last year I take a part-time job in the international camp for children. I have been telling one more worker will be needed this year and I think you are fit it. Why not to join us? The camp is at the foot of a small hill close to a river. It is so beautiful place! We can hear birds singing happy all around. Everybody sleep in tents,  that is very exciting. We usually work only five hours a day, so we will have plenty of spare time to visit the area and have funs. I am sure it will be an unforgettable experience. If you are interesting, reply to me soon.

Yours,

Jack
