Dear friend Mike,
I am writing to you to tell you about all the interesting things about my fair trade visit. The event was huge and I am amazed because I have seen many products that cannot be found in our country. I saw Australian, German, and many other products. The thing that was really interesting to me was the price, it was pretty cheap.
There were the latest products from many countries and I have bought you something and that is a surprise. People were very kind and everyone was talking about their business and travel.
I cannot wait to give you my present. You will be amazed.
Your friend, Dave.
