02.Rocket Science . Simple as this I'm laying the facts We walked through a maze And we can never go back The passion we missed Because of her act I sing this song bitterly, bitterly . So I reminisce of times in the past Don't know how we stuck We started falling off track Cause I feel dismissed We're fading to black I sing this song miserly, miserly . Now that I keep climbing You're losing grip You're far behind me And there's no sacrificing Something so simple How could she twist it all up To love it ain't rocket science Rocket science To love it ain't rocket science Rocket science . It's simple as this I'm letting her know I'm leaving, no traffic sign can stop me on the road Recalling her kiss How could she let go I sing this song bitterly, bitterly . How can we replace something that you erased You're such a criminal, criminal, criminal, criminal You're tearing down my roof but still I have no proof You're such a criminal, criminal, criminal, criminal . Now that I keep climbing You're losing grip You're far behind me And there's no sacrificing Something so simple How could she twist it all up To love it ain't rocket science Rocket science To love it ain't rocket science Rocket science . I hope you're safe and sound, girl I won't be around You're such a criminal, criminal, criminal, criminal How can we replace something that you erased You're such a criminal, criminal, criminal, criminal . Now that I keep climbing You're losing grip You're far behind me And there's no sacrificing Something so simple How could she twist it all up To love it ain't rocket science Rocket science To love it ain't rocket science Rocket science
