Translation of bluetooth in German

My mom and dad used to speak English when they wanted to say something I shouldn't understand. In this way I have learned English. I did not tell them till late, but I did understand every word they said.
Everything in your letter is perfect! Almost no errors and the writing style, very impressive! After this first year in England, you have also improved your vocabulary and the grammar skills.
Many thanks for the corrections. Exactly what I needed to be happy. I want to learn French because it's a great language and because it sound so romantic to me. There is a lot more to improve.
