Translation of Knochenbruch

I want to improve my level of English. Have you ever been in the U.S. and in which states have you been? I've been in England, Scotland and Ireland, but unfortunately, I have never been to America.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
If you want to write again in Spanish, just do it. I have much to do at the moment, again and again... Sometimes it happens that I must work at night until the early hours of the morning.
