she

You may not be her first, her last or her only.
She loved before, she may love again.
But if she loves you now, what else matters?
She's not perfect - you aren't either, but if she can make you laugh, cause you two 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 know's 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 known when she makes you mad and miss her when she's not there.
