Some Do, Some Don't

When you look at me who do you see
Do opposites distract you
When we choose up sides when the roads divide
Is it me you'll keep coming back to
You place a cautious bet a little late night roulette
It makes your heart beat faster
But when the hour comes - will you run
Or decide that it's worth chasing after
You don't have to - unless you want to
You don't need to - unless you need to
Some do some do some do some don't
When you start alone and end up alone
But between it's hours to play with
Is it black or white - we're talkin' gray tonight
Do you find the one you'll stay with
You try to release it but I'm not sure that
There's any reason to - just let your heart decide
On your way back home will you walk alone
Have you locked up the door behind you
Or take me in and all that I am
I'm here if you should decide to
