Note for the folks at home: "Rude", it turns out, is a relative term on a global scale. Things to do in Kenya: pick nose, cut forward in lines, chew with mouth gaping, spit freely, urinate in semi-public situations. Things to avoid doing in Kenya: scratch beard, greet someone with something as short as "hello", leave the house with dirty shoes, decline an offer of tea, use the imperative verb tense ("come!") instead of the subjunctive ("would you come").
