I'll add to "when the kids turn out good"..
My daughter graduated High School in 2002 and traveled 2800 miles away to college.
No dorms avaliable, so she and I drove cross country towing a small trailer. We rented her a small apartment for college. She graduated on time.. 4 years later (2006) with a double BA degree and found work. Although she still relied on dad from time to time as layoffs and rehires occured.
Her last year in college she found a great young man, employed and sensible. They were married in Oct 2008 and they bought and moved into their first house the week before Christmas 2009.
In the midst of home buying, they took time at Thanksgiving to travel 8hrs by car each way to visit her grandmother to hook up an internet, set up email and provide instruction. (He's an IT professional geek and set it up so he can I can remote into Grandmother's computer to "fix things".)
Everyone keeps asking my wife and I what we did differently. I don't think it's so much "different".. we always were "family", we spent time together, as she grew up and had opinions we listened and debated and valued what she had to say. There were boundries, she knew what they were, and as she grew up those boundries expanded or became her own.
Isn't life grand....
And to the OP.. wish the wife well with the treatments..
Merry Christmas and Happy New Year.
