I've always had a good relationship with both parents, but my relationship with them grew stronger after they went through a divorce. My mom now lives in DC and my dad here in Atlanta. My mom is very much the free spirit. She's already married and divorced again, works hard, plays hard, is a poker shark, and lives more livlier than most women half her age.
My dad on the otherhand is still recovering from the divorce. He lives alone in a large house in Atlanta suburbia (Hell), has two Master's Degrees but also two pensions, so he doesn't have to work and doesn't work, despite the fact that he should to keep his mind busy. At least he has a loyal dog. He keeps himself busy by going to his fishing cabin on most weekends, taking care of the dog, and going down to Jacksonville to take care of his ailing parents. But he just doesn't worry about his own happiness enough. He needs to regain his lust for life and find himself a nice woman again.
So, yes I am close to both. I worry about both. But I worry more about my dad. And I will be sad to move away from Atlanta (if I do). My parents have become more than parents. They have become reliable, trusted friends as well.
