Easier aid Than Done

Why don't you try harder next time.
You're better safe than sorry but I'm gone and never coming back again.
So now you think I'm crazy.
Now you know I'm not the one.
Who cares, she's gone away and left you sad and lonely.
The world you knew before is gone.
And you wish that she would call to say,
"you know I'm sad and lonely and everything before is everything I had."
So why don't you say sorry next time,
I said you're better safe than sorry but I'm gone and never coming back again.
Now you think I'm crazy.
Now you know I'm not the one. You would.
Pick out your answer when you're gone.
