I'm not much for quotes that have to do with love or friendship.
I tend more towards absurd banter: 'My body is a gift from God,' Jared said gravely. 'Except for my hips, which are clearly a gift from the devil.”
Or self power: She was the heir of ash and fire, and she would bow to no one.
With a smattering of bookish love for good measure “She had always wanted words, she loved them; grew up on them. Words gave her clarity, brought reason, shape.”
That being said, I have one quote about love that I feel very strongly about.
“I can listen no longer in silence. I must speak to you by such means as are within my reach. You pierce my soul. I am half agony, half hope. Tell me not that I am too late, that such precious feelings are gone for ever. I offer myself to you again with a heart even more your own than when you almost broke it, eight years and a half ago. Dare not say that man forgets sooner than woman, that his love has an earlier death. I have loved none but you. Unjust I may have been, weak and resentful I have been, but never inconstant. You alone have brought me to Bath. For you alone, I think and plan. Have you not seen this? Can you fail to have understood my wishes? I had not waited even these ten days, could I have read your feelings, as I think you must have penetrated mine. I can hardly write. I am every instant hearing something which overpowers me. You sink your voice, but I can distinguish the tones of that voice when they would be lost on others. Too good, too excellent creature! You do us justice, indeed. You do believe that there is true attachment and constancy among men. Believe it to be most fervent, most undeviating, in F. W."
In my completely objective opinion, I can tell you that this is the best love confession. Of all time. Ever. Always. There will never be a love confession that will make me swoon harder than this one. It's no surprise it comes from the Queen of love stories - Jane Austen. (I'm just pretending Mansfield Park never happened.) While Pride & Prejudice might be the bread and butter of my romance tastes (I love a good hate-to-love story), Persuasion will forever reign as the majesty of all love confessions ever.
