My parents have been popping up quite a lot in my writing lately. Maybe it is a stage-of-life thing. Here is a quote my father knows by heart:
"I do the very best I know how - the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what's said against me won't amount to anything. If the end brings me out wrong, ten angels swearing I was right would make no difference."
- Abraham Lincoln
