1. Well, your floors are dark, dark, dark, dark brown (beautiful really, but sort of a pain in the cleaning department) and are always showing something on them.
2. You can see footprints on said floor from not only your own family's shoes, but visitors that came at least 2 weeks ago.
3. On that note: it's been at least 4 weeks since you last mopped.
AND LASTLY! You go to sweep up the flour that has been pushed on the floor from your earlier cookie/doughnut (more on that later) making venture and the flour ends up really gray, not white. Yummy.
