That's such an unkind thing to say about another person's life. He seems like a contented and inoffensive person, and he's quietly living the only life he'll ever have. There's real dignity in that. I do wonder why you wrote this.

As for children: being a parent myself, I think it's best not to instrumentalise them by viewing them as a legacy that you'll leave behind after you. They're their own people. They don't owe you that obligation.
