I'd expect the duty I have to my family to be of bigger importance than a commercial contract.

Does your duty to the family derive from the legal system of your country? Would your duty to your family change if some laws about who can sue whom for what changed?

Do you always seek to portray the people you are talking with as horrible monsters?

I didn't mean to say anything about you personally. I used "you" in the sense of generic you.

But I am curious, which part did you find implying being a horrible monster?
