• I Write Sins Not Tragedies


Dust is a general name for minute solid particles with diameters less than 20 thou (500 micrometers). Particles in the atmosphere arise from various sources such as soil dust lifted up by wind, volcanic eruptions, and pollution. Dust in homes, offices, and other human environments consists of human skin cells, plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, and many other materials which may be found in the local environment.

    Imagine how a single dust particle which we think goes against our hygiene is actually traveling all the way from around the world; a volcano or a mountain or an oceanic rock or a bone of an extinct dinosaur :O there can be beauty in literally everything O_o
