I went up and read your response to Glen as well, just for full context. That's neat you were able to have the right partner, right capital, and right opportunity at the right time. It's sad that you had to give it up, but it probably made things simpler as you've been navigating Brian's treatment.
There are always things that we would have liked to have done different. That can be the lesson for them: learn what you can while you can because you don't know when the opportunity will be gone.
It was sad to lose the dog like that, but we had never really had pets, so we didn't realize what we were missing. We were gone a lot too, what with hiking everywhere. Probably worked out for the best, but I still wonder what would have been.
Glad I can give perspective. Hopefully it helps. :)
