Translation of cheery in German

Sometimes you forget one word and this makes the entire sentence sound differently. That means that you need to read each email before sending it twice at least if you want to be on the safe side every time.
This afternoon I will fly to Chile. My two brothers and sisters live there. They are also very old and my brother has already died. My parents emigrated 30 years ago, but they wanted to stay.
I am glad that you accepted my offer. I would like to write letters and emails in English and if you want you can write back to me in German. I want to correct your German and so we will both get better.
