Isn't It Funny?

Isn't it funny how one day you're the light that gives someone light

And the next day they might as well not even know who you are

Isn't it funny how one day someone says you're their world

And the next day they don't want you

Isn't it funny how one day you love me

And the next day you love her

Isn't it funny how you told me you would never hurt me

And the next day I am crying on the bathroom floor because you decided I wasn't enough

Isn't it funny how one day I've had enough with you

And the next day you're broken and wanting me back

Isn't it funny?
