In a true partnership, the kind worth striving for, the kind worth insisting on, and even, frankly, worth divorcing over, both people try to give as much or even a little more than they get. "Deserves" is not the point. And "owes" is certainly not the point. The pont is to make the other person as happy as we can, because their happiness adds to ours. The point is -- in the right hands, everything that you give, you get.
