Yup, for me I value the familial relationships more than the romantic ones (though I consider the family the most romantic thing ever!!) and I really love Parents-Children stories, especially those were they're not blood related.
You should treat your elders like how you want to be treated when you become old and weak, it's sad that people in my country started to move to the USA mindset of not respecting eldery so much (though we still do, just less than before).
As for parents, while Islam teaches us to respect and be kind to them even if they didn't do that to us, Islam also teaches us to help our children to respect us by not treating them with injustice.
One of things I say to Muslims who doesn't understand Islam, that it is Perfect (Or should I say Integrated?) religion... Any rule that seems too harsh is countered by a rule that softens it. That if you took some of the religion teachings and discarded the rest... You'd be either too weak/naive to protect yourself, or turn into a killing machine. I'm sure you heard about these two types of muslims @carolkean.
