Once Upon a Time, there was a young man with a beautiful face. People loved the young man, but he never showed interest in loving anyone, because all he loved was himself. When the young man, who neglected to love and sought only to be loved back, found someone he truly cared for, he realized that he had lost the words to express those feelings...
I'm sorry Li'l. I didn't mean for this to happen. I never wanted to hurt you. I think you're wonderful! I'd choose you if I could, but I'd already offered my hand to Hazel. If only you and I had met sooner...

It's like a disease! I slept with [her] one time, and I caught feelings! I caught feelings bad! I used protection and everything!

[Angrboda] saw herself through [Loki's] eyes - so solemn, does she never smile? But there is that fire behind her eyes. Nothing stands in her way. Any other woman I could run over, but not her. She is a cold red lily with steel knives for petals, a sleek and beautiful beast with deadly fangs. I wonder if I could make her smile. I need to make her smile - but all I do merely angers her! My charm falls as nothing at her feet. No, I know that she would settle for no compliments, no charms, no words even. Nothing less than my soul. And I long to give that to her...but I am so afraid. I am so afraid that I cannot even speak of it. I cannot speak, and that is something that I will not have-
Well, he told her, "I used to daydream about an infinity of women, all beautiful and accessable. But I found you were pretty and then some"

Lily: Barney, how can you be in love and still be sleeping with anything that moves?
Barney: I'm sorry, I don't follow you. That's like saying, "How can an ant carry twenty times its body weight, but root beer floats are still delicious?" Are the two even related?
Once you're kissed by Amy,
Tear up your list, it's Amy
Ply her with bonbons, poetry and flowers
Moon a million hours away...
You might be quite the fickle-hearted rover, so carefree and bold,
Who loves a girl and later thinks it over and just quits cold.
But once in love with Amy, always in love with Amy.
