You know what annoys me?

is how often people don't remove their lint from dryers or check the lint trap before drying.  Not only is it a fire hazard, but wastes electricity, quarters, and time.  I've been using community dryers for the last couple years and believe me there are people who just run the dryers without checking the lint trap, making the rest of us wait while their clothes dry slower and slower.

I like to reuse my lint for plant-potting material.

Dryer balls definitely save  time and energy, while softening your clothes --well worth the 10 bucks (you can find them at Walgreens too).
