It doesn’t matter that the trash has been overflowing for days. It doesn’t matter that taking out the trash is his job. He won’t notice. Just take the trash out yourself.
Or, alternatively, you can always reframe your laziness as righteous indignation:
"But it's been overflowing for days! Taking the trash out is his job! I'll just pile a few more things on, and he's bound to notice!!"
(When in doubt, take a picture and blog about it.)
