I've read this several times before, and this bit always gets me, as they say, "right in the feels":
“Don’t worry,” I said. “They’ll be fine. Your kids will remember you as perfect in every way. They didn’t have time to grow contempt for you. Your wife will cry on the outside, but will be secretly relieved. To be fair, your marriage was falling apart. If it’s any consolation, she’ll feel very guilty for feeling relieved.”
It's just so human. It's almost confrontational in its degree of, "That's just how shit is sometimes," but it's delivered with utter compassion. That juxtaposition captures so much of how I feel about the human condition.
Now that you've described it like that I realize that evoking that feeling is the selling point of most literary fiction. I also feel a bit ashamed I didn't realize this earlier. It's more precise than just saying something has "realistic characters".
