Tell me it's not so

Tell me it's not so, tell me a lie,
Say you won't go, say you won't say goodbye.
Tell me forever and that times they don't change.
Say you're not leaving and that you'll always feel the same.
One smile for the last time, one smile for today,
One smile that the darkness has taken away.
But your smile's just a memory that won't go away
And I'll always remember your smile today.
And I'll always remember your smile for today.
