Gregor,
If your parents won't listen to/understand you...why would they listen to me?
It's almost impossible to define a person concisely...opinion is required.
If there were a reliable way to define a person, I would think that it has to do with evaluating and judging the questions one asks. Questions show where a person is coming from...so to speak. Questions reveal intentions...indirectly.
The questions you ask reveal you as a person who genuinely cares about others. They show the fact that you have an excellent grasp of a 'bigger picture'.
Keep asking those important questions.
You will find the answers within.
