Loving him is like driving a new Maserati down a dead end street
Faster than the wind, passionate as sin, ending so suddenly
him is like trying to change your mind
once you're already flying through the free fall
Like the colors in autumn so bright just before they lose it all
him was blue, like I'd never known
him was dark gray, all alone
him was like trying to know somebody you never met
But loving him was red him was red
Touching him was like realizing
all you ever wanted was right there in front of you
Memorizing him was as easy as knowing
all the words to your old favorite song
Fighting with him was like trying
to solve a crossword and realizing there's no right answer
Regretting him was like wishing you never found out that love could be that strong
