Translation of What a pity in German

I would like to give you a proofreader's project. Proof reading sample sentences that were entered into the dictionary by our users. It is a very tough project and needs a lot of discipline and patience.
The last sentence is the hardest in the entire series. Writing may bore some people, but it is considered the best training in language learning. It is a skill that can lift you from intermediate to advanced level. Do not neglect it.
I apologize that I have not written for such a long time! Please call me on my new phone number, that would be great! How is your son feeling, has he been recovering? I am sure that he will be fine.
