Hi apsu,
thanks for your questions.

1. I had considered, but as @arrjey informed us, no one would have understood except for Germans
2. From my perspective, to be honest, I do really have some good friends. I am the one who does not work for the tax authorities, but I try to help people to find a good way through the jungle of taxes.
3. I am not sure if I understand your question correctly. So, from my perspective, I am a guy whose job is dealing with taxes every day
