When your work is criticized, you don't have to panic that everyone secretly hates you. You can kill your own food. The garage is all yours. You get extra credit for the slightest act of thoughtfulness. You see the humor in Terms of Endearment.
Nobody secretly wonders if it's silicon.
You never have to clean the toilet. You can be showered and ready in 10 minutes. Bodybuilding is natural. Wedding plans take care of themselves. If someone forgets to invite you to something, he or she can still be your friend.
