“One of the troubles is this: the heart isn't heart-shaped.”

“It isn't enough for your heart to break because everybody's heart is broken now.”

“The stems stood tall and straight, one series arranged in a single line, the other in a crudely shaped heart, the final one in the shape of the letter U. I love you.”

“Hearts with one purpose alone
Through summer and winter, seem
Enchanted to a stone
To trouble the living stream.”

“I really am a happy, amusing fellow at heart. Trouble is I seem the only one left.”

“This hole in my heart is in the shape of you. No one else can fit it. Why would I want them to?”

“Heart, fear nothing, for, heart, thou shalt find her- Next time, herself!-not the trouble behind her”

“Let not your heart be troubled, neither let it be afraid.”

“I got my heart's desire, and there my troubles began.”

“Isn't strength the ability to renounce every lie in your heart?”
