Angelina that is not exactly defined and can be anything and everything (do you understand my problem with such laws)
You can find examples of court rulings that narrow it down. As an example I found one where a 16 year old girl went to court because her parent was against a relation with an 30 year older man in Berlin. She was able to clearly explain in court how important the relationship is to her. The court decided that the relationship is very important for her emotionally and for her further development and forbade the parents to hinder it.
It can't be anything. For your situation the court will decide for your relation. In your case, the court would most likely decide for your relationship to continue undisturbed.
Laws in Europe are much clearer than in comparison with countries of the Commonwealth. For them, what is decisive is what the current legal perception becomes. That is why the court is presented with the judgements that have been decided, to show what it is. The opposite side tries to hold with other judgements against it. Also with us there is room for interpretation, however, always within the law.
Angelina PS: My suggestions are not always in the legal frame, but as I said, this is a PRIVATE MATTER
Yes, it is and I sad already, you decided in this way because for you it is the best solution. I accept it.
The starting point was not your compromise it was the question whether your father is aware of what he is really doing in the overall context of our democracy with its rights and duties.
