2 父と子

In my younger and more vulnerable years my father gave me some advice
that I've been turning over in my mind ever since. "Whenever you feel like
criticizing anyone," he told me, "just remember that all the people in this
world haven't had the advantages that you've had." He didn't say any more,
but we've always been unusually communicative in a reserved way, and I
understood that he meant a great deal more than that. In consequence, I'm
inclined to reserve all judgement, a habit that has opened up many curious
natures to me and also made me the victim of not a few veteran bores.
