Are You a Mirror (...Or a Window?)

Oh little baby, you are fragile and weak, so I will hold you til you fall asleep. I look inside you and I see myself. I will love you, I will try and be strong, though, my bones are aching and my days are long. You'll look inside me and you'll see yourself, as I look inside you and I see myself. And one day you will look me straight in my eyes and judge me for the things I've been in your life. I hope you love me when you know me well, because I look inside you and I see myself.
