Kids are magnets for objects. Especially plastic objects. There may be actual magnets for the industrial sorting of recyclable plastics, but I suspect that children are the most efficient tool for categorizing plastic by color. Adults, out of the noble instinct to care for those who are smaller and cuter, want children to be nourished, entertained and well-armed for battle with gender-appropriate pink toothbrushes and blue bicycles. But what if Hello Kitty was blue and Superman was pink?
Of course I am worse than all the kids combined, as I acquire at a frantic pace and have also been photographed amongst my nearly monochromatic tableau of rust and wood.
