Not What I Expected Lyrics

i've got a vision in my head
of how it should be
and i wonder if that's how it will
work out
when i sit down will i be smiling
a grin on my face
or will i just want her to
get out of my head and my mind
that's how it goes
sometimes i think it will be so right
and then she shows
and it's all wrong
i feel her hand touch on my arm
and my skin grows cold
how can this be
why's it so fake
and why's it so false
how should i tell her she should go
cause it's all my fault
i let my heart get ahead of my mind
and everything else
