“True friendship is a promise you keep forever.”

“Promise me no promises,
So will I not promise you:
Keep we both our liberties,
Never false and never true:
Let us hold the die uncast,
Free to come as free to go:
For I cannot know your past,
And of mine what can you know?”

“Friendship's best,' I said, 'and friendship's forever because no baby can come along to spoil it.”

“Don’t make promises you can’t keep”

“What you keep to yourself you lose, what you give away, you keep forever.”

“It was in their friendship they just wanted to run forever, shadow and shadow.”

“The only true test of friendship is the time your friend spends on you.”

“And you treat me wonderfully and keep all your promises.”

“Rare as is true love, true friendship is rarer.”

“Do not keep on with a mockery of friendship after the substance is gone — but part, while you can part friends. Bury the carcass of friendship: it is not worth embalming.”
