Things don't always fall the way you thought they would.
Raccoon poop is much larger than you would imagine.
If you could throw boards and shingles into a 20-yard dumpster for hours every day, you would never need to go to a gym to lift weights.
If your husband gets scratched by a nail, and his tetanus shots aren't up to date, he has 48 hours to remedy that.
If a board falls on your toe, and it hurts, just because you decide to ignore it, doesn't mean it probably isn't broken.
