Fun Fact:

Now, I know a family whose whole idea of having fun is to have a conversation where everybody blows their own trumpets.

I still don't do that, hence, I guess, I am still an outsider. And probably, that's why I am yet to understand their idea of happiness, or feel it.

There are some people with such hard exteriors...

that even someone else's feelings and raw emotions won't penetrate them. Not even their partner's.

Freedom and responsibility!

You will have to learn to conciliate freedom with responsibility,  understanding that freedom is not given to the one who earns it, and that responsibility is not synonymous to obligation.  Enjoy the company in a leisurely way.
