Everything good comes with a price.

You came with the cost of my free thought,
And my flirtatious disposition,

Friends come with the fact that you will alwyas have to be there for them, support them no matter what, be burdened by their death and mistakes.

Good grades come with sleepless nights and devotion to mindless work.

Life comes with sorrow and grief as well as madness and terror.

Books come with the fact that if you read them to the end, you will be sad cause there is no more to it ocnce you are done with it.

And the list goes on, from simple things, to everything.
Think about it.
