There are people in life you meet that you just know will be bad for you. People oozing with charm and laughter and magnetism, so much so that you just want them all to yourself. You stare and you're distracted, you want and you're so lost--how could you, small and ordinary and dull, know her at all? Your heart, your breath, it's all putty in his hands--and you don't even care. You do stupid things for her sake, want to be the way that he is. And before you know it, you've given a part of yourself away, and want it back but you don't really; you're tangled up in him.
And he'll toy with you. They'll laugh and charm with you, play the game older than us all with the same grace they approach everything else. You remind yourself she's bad for you. You tell yourself to get over it.
And then you go right back to the first place, where you laughed and charmed, and were charmed. And you're enchanted, changed--and you don't know how to become disenchanted, unchanged.
