I loved this article. Short but true. I would add just one thing: you can change your parents--but only if you change the way to interact with them. And I would never say it always works. But here's what happened to me:

I struggled for years wishing my mother was more caring and affectionate. She always did the best for us, but never had time to show love in the obvious ways.

I read somewhere "if you want to change the way someone relates to you, you must first change the way you relate to them."

I meditated on that a long time. And I realized that I needed to model for her the way I wanted her to treat me.

I started by not reacting to her criticism; I would say instead "thank you for that" or some such thing. It was hard! The other thing I consciously did was to start asking how she felt, if she needed anything, was she doing okay? I showed the kind of concern for her that she never seemed to show for me. When I fell back into old habits and lashed out at her, I apologized immediately and told her I loved her.

It took three years, but the effort was worth it. She tells me she loves me all the time now. And she hugs me every time I see her. I finally have the relationship I wanted with her. So don't give up. If a person is truly important to you, show them the way. If you are equally important to them, it might work.
