Dear ....... (name of your friend)
I just returned from my trip to Hawaii.
First of all, it was so exiting and fun. I wish you were there to see all of the little turtles relaxing on the shore or me trying to learn how to surf. Guess what- I was unsuccesful. Second of all, you won't believe how hot it was. Here I was walking at the beach dying of the hot sun burning me. Thirdly, I really learned about Hawaiian culture and people. It was nice writing to you this letter. It made me remember all of these wonderful times! Hawaii is truly a very beautiful place to go to.
see you soon.
