My room is dusty. *COUGH* *HACK* *COUGH* This apartment is dusty. *COUGH* *COUGH* The whole building is dusty. *COUGH* *RETCH* *COUGH* Got me wondering... what is dust anyway? -The particulate remains of planets long since destroyed? -Miniature alien spaceships? -God's dandruff??? what do you think?
