To be honest, I don't. I don't have parents who are that poorly yet, but the bottom line is that I have a much closer relationship with my dh than with either of my parents, and I just don't feel the need to be there much for them. At some point I will have to, since I'm my mother's only living child, but she lives abroad half of the year and chooses not to see us much even when she is in the country, so we're fairly distant and I don't feel obliged to be a very "good" daughter.
It sounds like a tough situation, my sympathies!
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
