Human nature is a funny thing, You been out there all these years. No explaining 'bout this chemistry, as I wipe away these tears. I been staking out your neighborhood, and my eyes are open wide..... You're All I Need, my little heart is aching. You're all I see, don't let my heart keep breaking. I been trying to make you notice me, but you'd think I wasn't there. I been saving my best jokes for you, as if you could really care. I been leaning on my sanity, but it's time to let it go..... You're All I Need, my little heart is aching. You're all I see, don't let my heart keep breaking. I been staking out your neighborhood, you can always count on me..... You're All I Need, my little heart is aching. You're all I see, don't let my heart keep breaking
