“Jonathan Dimbleby: Understandably, when your marriage collapsed, you form close friendships, you re-establish close friendships, of whatever character that friendship is. Were you, did you try to be, faithful and honourable to your wife when you took on the vow of marriage?
Charles, Prince of Wales: Yes, absolutely.
Dimbleby: And you were?
Charles: Yes, until it became irretrievably broken down, us both having tried.”

“I, Charles, Prince of Wales, do become your liege man of life and limb and of earthly worship and faith and truth I will bear unto you to live and die against all manner of folks.”

“You can date the evolving life of a mind, like the age of a tree, by the rings of friendship formed by the expanding central trunk. In the course of my history, not love or marriage so much as friendship has promoted growth.”

“Sometimes defining friendship can be simple. If your heart still aches after someone has passed, then you were a true and close friend. They may have physically left this world, but they still walk among us in our hearts.”

“If you held your fire until you were very close, you seldom missed.”

“Try having a relationship with someone and see if you can establish any sort of friendship without faith. Walk up to a woman and introduce yourself. When she tells you her name, say, 'I don't believe you.'… Carry on like that for a while, and before long you may be nursing a black eye. Your lack of faith in her is a strong insinuation that she is a liar.”

“The strong bond of friendship is not always a balanced equation; friendship is not always about giving and taking in equal shares. Instead, friendship is grounded in a feeling that you know exactly who will be there for you when you need something, no matter what or when.”

“Marriage is the cure of love, and friendship the cure of marriage.”

“Friendship is the marriage of the soul, and this marriage is liable to divorce.”

“They adore you beacause they think you offer up your friendship and ask for nothing in return. But that's not true-' He took a deep breath. 'You do ask for something. You ask that we never expect you to need us.”
