Translation of castaway in German

When I don't study I go for swimming in the pool or make some sports with my friends, such s Tennis, soccer...Why do you like to learn Spanish? Do you want to make a trip to Honduras or to Nicaragua?
Thank you for your kind mail. I guess that we are friends now! The last winter was extremely cold. Now in Summer the weather is nice. My English is terrible but i hope that you will give me a chance.
I'm writing you in English because I don't have a lot of time and writing in German will take me a long time. Just a few corrections: you can not say in English How you do, you need to say How do you do...
