The jovial Mr. Shetty told me over the phone that people have no idea of the scientific knowledge required to produce glitter, that Glitterex’s glitter-making technology is some of the most advanced in the world, that people don’t believe how complicated it is, that he would not allow me to see glitter being made, that he would not allow me to hear glitter being made, that I could not even be in the same wing of the building as the room in which glitter was being made under any circumstance, that even Glitterex’s clients are not permitted to see their glitter being made, that he would not reveal the identities of Glitterex’s clients (which include some of the largest multinational corporations in the world; eventually, one did consent to be named: thank you, Revlon, Inc.), and that, fine, I was welcome to come down to Glitterex headquarters to learn more about what I could not learn about in person.
