Translation of Etüde

Dear Arnold, please send me David's contact details. I will arrange a meeting and present him the machine, so that he will know how to operate it properly. Thanks again and all the best.
After that I expect that you do the same. Write me a text in English and the same translated to Spanish. This way we will learn all directions. We will be able to compare the texts and learn.
Anyway, on our last day in Sapa, we hired a taxi driver, payed him twenty dollars and asked him to drive us around for a few hours. We had the Tram Ton pass in mind which separated two climate regions.
