Good things about dust:
1) Vacuuming is exercise.
2) Dust is the soil of the domestic domain. So it’s like Adam’s cousin. Which means dust is family. And we like family.
3) Without dust many of us would have less allergies and without the burden of allergies we might be less dependent on dust-elimination and then what kind of people would we be? So dust makes us become the people that we are and must be in Hashem’s plan for the best. B”H.
