I think maybe when you live with someone who is really very ill for a long time, it somehow gives you more of a greedy appetite for life and maybe, yes, you are less measured in your behaviour than you would otherwise be.
No, only disappointment in myself on those occasions I didn't manage to rise to the occasion as I felt I should've done. I can always see how to do it, and then the challenge is, Can I manage that each and every day?
