1. Your grandpa's horse's dandruff is in the shower.
2. The raisins on the counter are crunchy.
3. You can stuff a pillow with the rat fur on the couch alone.
4. Your nightstand is jammed with garbage from middle school.
5. Clay dust from your old arts-and-crafts project is in your AC.
6. There are a hundred roach-sized headstones littering your cabinets.
7. Your cleaning supplies are only in your closet for show.
8. People hit the gas every time they drive down your street.
9. There's a dust bunny colony in your sheet.
10. You don't even have much of a sheet anymore.
