Translation of Walkman

I want to work on the country specific terms first, then do a revision of the words that we have entered so far... please give me a few days to finish it. However, I may need to contact you over the weekend, depending on my progress.
I usually do not travel, and if I do, then only to England, when I visit my parents who live in a suburb of London. I can not afford to travel too much, because it is a very large expense.
I have problems with adjectives, endings and articles. The grammar is so difficult. I am very happy to learn Spanish with you. What went wrong with the lessons? Thanks and best regards.
