I rule my life by my voice of reason

It whispers things like
You're going to die sooner than later
Other people matter more than you
You need to act happy

And when my toddler emotions dare to question why
Reason preys on fear, their weakness
Because otherwise everyone will know the truth

Would that really be so bad?

Always the experimentalist, it calculates
It wouldn't take very long to fall off the window sill
What if we just didn't get up?
The voice of reason whispers
Death, death, death, death

For a voice of reason, it's not very reasonable
It is more a voice of cold, detached apathy
Speaking in lies and flawed logic
I know it is not to be trusted

So then why do I still listen to it?
