Translation of diablos

I work as an actor in the theater. I have studied English for seven years, French and Spanish for two years. Well, my level of Spanish is too low to have a good conversation, but I understand it.
Yes, but on the other hand, using full, simple sentences also helps people who are learning the language more than just the short clauses. It is probably a mix of both, but I have not decided yet which ratio is the best for us.
I'm fine, thanks. I'm sorry that I did not write back to you sooner. As you see I am very busy with my work. But I'll take the time to help you because I promised to do so. So let us start soon.
