Ticking Time Bomb lyrics

I always find a pic by the phone when I find myself alone, and I write a love song about you. You ask me if I'm blue and I tell you that I'm happy just thinking about you. You've turned my heart around and you let me see a side of you that no one else has seen. The lights are turned way down and you're whispering your thoughts, your fears, your worries and your dreams. Do you know I worry on the inside, I will find out that you were untrue. My friends all tell me you're a ticking time bomb (he's a ticking time bomb) I worry that you'll break my heart in two.
