This is just the beginnign of one of my songs. I figured I'd see how people like it before I put the whole thing on there yet. I'm new to this site, so I'm still figuring things out....

Who Knew

I think of all our good times
every single little laugh
it's painful enough to say
those things are in the past

who knew
I'd ever be her
who knew
i'd be crying all these tears
I thought you were someone
that didn't exist
guess you were the exact opposite
i keep waiting for you to tel the truth
who knew
that's something you're never gonna do?
