Just when you think that you know where you stand   You've got the world in your hand   Just when you're sure of a dream that you plan   That's when the scenery changes   It changes      Just when you think that you know all the facts   You hold the whole ball of wax   You've got it made, you can start to relax   That's when the world rearranges   And changes      Someone that you really cared about   Someone that you couldn't live without severs the ties   All at once you're all alone and scared   All the happy hellos that you shared change to goodbyes      Why must we pay for hellos that we say?   Pay when we say our adieu   Just when you're sure that you're safe and secure   That's when it happens to you   It changes      Someone that you really cared about   Someone that you couldn't live without severs the ties   All at once you're all alone and scared   All the happy hellos that you shared change to goodbyes      Why must we pay for hellos that we say?   Pay when we say our adieu   Just when you're sure that you're safe and secure   That's when it happens to you   It changes
