You like someone when you know the best side of him and like him, but when you Love someone you know the worst side of him and you still love that person with everything you have in your heart. We are all a little weird and life's a little weird, and when we find someone whose weirdness is compatible with ours, we join up with them and fall in mutual weirdness and call it love.
"You may not be her first, her last or her only. She's loved before, she may love again. But if she loves you now, what else matters? She's not perfect, you aren't either, and the two of you may never be perfect together. But if she can make you laugh, cause you to think twice, and admit to being human and making mistakes, hold on to her and give her the most you can. She may not be thinking of you every second of the day, but she will give you a part of her that she knows you can break: her heart. So don't hurt her, don't change her, don't analyze and don't expect more than she can give. Smile when she makes you happy, let her know when she makes you mad, and miss her when she's not there." -Bob Marley
