Laundry.

We like having nice clothes. So why do we complain when we have to do laundry?

We like having a clean house. So why do we complain when when we have to vacuum?

We like driving a working car. So why do we complain when we have to get an oil change?

We like having people help us. So why do we _______ when we have an opportunity to give our time?

We all have to fill in the blank for ourselves.

(And yes, I complain about doing laundry.)
