When you say no from the outset, you limit the possibilities of oppression.
If you say no, early in the cycle of oppression, and you mean what you say (which means you state your refusal in no uncertain terms and stand behind it) then the scope for oppression on the part of oppressor will remain properly bounded and limited. The forces of tyranny expand inexorably to fill the space made available for their existence.
We do not love people so much for the good they have done us, as for the good we do them.
Love does not consist of gazing at each other, but in looking outward together in the same direction.
It is not a lack of love, but a lack of friendship that makes unhappy marriages.
