Dear Mom,

I am staying at aunt Chi' home in Nha Trang. The weather is very nice here.People are friendly and the food is a bit sweet. I have been to Tri Nguyen aquarium. I took a lot of photos and bought some souvenia for my friends.I bought a nice present for Mom and Dad.I think that it will be a big suprise for Mom and Dad.I wish you were here with me. I will come home in three days. Hope to see you at home

Love,
