Dear xx：
I can't believe my trip is almost over. I came to Easter Island just two weeks ago.I was with a group from the university.We stayed with families that live on the Island.We studied the stone statues,called moai,and the cave paintings.I really learned a lot .I'm tired,but I love every minute of my trip.
Take care,Margaret
xx
