Unethical Employment?

A layer of dust instantly covers everything in Kabul – my face, my laptop, my books.

The flies are aggressive, they land on you and will hardly be shooed away: “Get lost, I was here first.”

Each day I go out, I "employ" two of the beggar kids Anayatollah and the Map Kid at one dollar a day. Their job is to keep all the other beggars away from me (I can't claim credit for this idea). It works well. They joke with everyone that they are our bodyguards. My seven year old bodyguards.
Probably unethical, but I have an easier time.
