Only weakness is _____

The thing is, I won my first game of hide and seek when I was very little. You looked for hours and upon my finding I just smiled. I couldn't help it, you were part of me yet you didn't know me at all. That's what my smile said, kind of sort of, but it did. I've become so good at this; hiding, concealing, avoiding, keeping my mind on lock. But see the thing is this, you do know me. You do, you do, you do. You know there's love bursting from my heart and words spilling out of my mouth but you know I'm afraid of letting things out. Letting someone see my cards, nearly terrifies me; I get pushed but I always get even. I've always turned into that someone you miss.
