“If someone sticks by your side through your worst times, they’re the ones who deserve to be with you through your best times.”

Variant: When someone is in your heart, they're never truly gone. They can come back to you, even at unlikely times.

Papers of the Adams Family (1939)
Variant: Loyalty to country ALWAYS. Loyalty to government, when it deserves it.
Context: In a monarchy, the king and his family are the country; in a republic it is the common voice of the people. Each of you, for himself, by himself and on his own responsibility, must speak. And it is a solemn and weighty responsibility, and not lightly to be flung aside at the bullying of pulpit, press, government, or the empty catch-phrases of politicians. Each must for himself alone decide what is right and what is wrong, and which course is patriotic and which isn't. You cannot shirk this and be a man. To decide it against your convictions is to be an unqualified and inexcusable traitor, both to yourself and to your country, let men label you as they may. If you alone of all the nation shall decide one way, and that way be the right way according to your convictions of the right, you have done your duty by yourself and by your country — hold up your head! You have nothing to be ashamed of.
Only when a republic's life is in danger should a man uphold his government when it is in the wrong. There is no other time.
This Republic's life is not in peril. The nation has sold its honor for a phrase. It has swung itself loose from its safe anchorage and is drifting, its helm is in pirate hands.
