Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I haven't hit this, but my parents have, since they no longer travel. My dad mentioned how he'd never see his older brother again. A couple of us offered to travel with him (he's much more fit for travel that mom is, just can't see well), but he said no.
Reminded me so much of the movie THE STRAIGHT STORY. Here's a clip (best part about brothers begins at about 2:30.) I think this story encapsulates a lot of what we're talking about in this thread. YMMV
