Mechanical

I'm starting to see the patterns
Your mind works like gears
There are many hazards
But you won't break for years

If you are the machine
And I the mechanic
If I am nowhere to be seen
Will you start to panic

If my grease-stained heart
Gets caught in your wheels
I will be unable to part
Without scraping against steel

You don't need me to fix you
But you have convinced yourself otherwise
No, not just anyone will do
Because everyone else you despise

And you expect me to polish, upgrade, and mend
But you hold on far too tight
And I'm starting to bend
Dear, there's no end in sight
