Well, my Dad and Step-Mom died quickly from quick moving cancer... The only thing good about that was that it was quick and they didn't spends years suffering. It just fucking sucks because they were too young and my kids will never get to know them.
But my Mom is healthy physically, but is a borderline mental case. She's sold most of her possessions, left home in Denver to live in a studio in Chicago. She doesn't have any close friends because she ends up alienating them. She's already borderline alienated my wife. My wife puts on a cordial face when my mom visits (bless her), but any hope of a close relationship there is out the window.
My mom travels extensively on a limited budget. Egypt, Morocco, Europe, Central/South America. She always goes solo because she travels so frugally and no one in their right mind would want to spend 7 days with her in a foreign country.
That all said, I'm happy that she's content doing her own thing. I can only stand spending a few days with her at a time. I call her at least weekly and that seems to work for her.
My brother and she are oil and water and they are always at each other throats. So one day, when she's going to need help comes, it'll be up to me... somehow. She has no desire to come to Texas... So I have no idea how's going to play out. My wife said she'll help in any way she, even if it means we have to move her in... The thought of it scares the shit out of me.
I can go into detail about her in anyone is really interested, but I don't want to turn this into a mom bashing post.
