A second on this as my favorite climbing quote from a movie.
For climbing literature: "Good judgement comes from experience. Experience comes from surviving bad judgment."
From personal experience: This needs a set-up. Both of my kids (6 yo boy, 4 yo girl) are adopted from Vietnam and China, respectively. This costs several thousands of dollars to do, and there's not much in the way of "receipts" for sums paid along the way. At home one day last year or so, my son was becoming increasingly irritated with his little sister, who had been baiting him mercilessly for the better part of a couple hours...
At his wits' end, he asks me, "Daddy, can we just take Elaina back to China?"
Me: "Well, you know we can't do that, son."
Son: "Is it because we don't have the receipt?"
