There’s an immensity of love that bursts from your chest the first time you hear your child cry, every emotion you’ve ever felt is amplified to the point of absurdity, children open floodgates inside us, upward as well as down. You’ve never felt so happy, and never felt so scared. Don’t say “don’t worry” to someone in that position. You can’t love someone like this without worrying about everything, forever. It hurts your chest at times, a real, physical pain that makes Johnny bend over and gasp for breath. His skeleton creaks, his body aches, love never has enough space.
