Food v. Poop

I used to think your annoying quirks were cute
You found my maddening inflexibility a rock

Your insecurities and my disorders,
Each downplayed through unsustainable effort,
Were problems we could solve together

When the cracks show, is it darkness or light escaping?
Do I/you love/hate you/me in spite of/because of ?

The only difference between being full of food and poop is time
