This song was created through life experience. When you truly love someone and they truly love you back but will not let you completely into their heart because of the past pain they have dealt with. This song was created to insure people that fearing pain in understandable but experiencing pain is what makes you grow. It's what makes your love strong. Fearing pain and running from it will ultimately make you alone. Wearing your heart on a sleeve is the only way to find love because if you hide your heart from the world how can love find it? "Let Me In" was created to give people that strength, take away that fear and tell them that its ok to love again.
