If you love her, tell her so.
If you don't, she'll never fully know.
If you love her, notice the little things.
Like when she changes her style.
If you love her, when she's sad try and make her smile.
If you love her, hear what she is trying to say.
Think of how she feels.
If you love her, really know her, know what she would pick or say.
But most importantly if you really love her, when things get rough, stay.
