What's The Point ?

You said it once
Said it twice
Said it hurts but I do it again
I don't change, I don't learn
Cause I can't let it end
Said it's gone
Let it be, cause you don't need a friend
Maybe I do
I pull and you push
And we cry till we laugh again and I
I promise you
You promise me back and then
Why does it all fall apart in just a matter of time?
