"The Mashco had a ritual greeting: they hugged visitors, put their heads on their shoulders, and then felt inside their clothing, as if to ascertain their sex."

"For perhaps forty minutes, the two groups mingled: the Mashco touching and probing, and the Nomole team acquiescing, mostly in good humor. The Mashco women approached Flores and, as she giggled, touched her breasts and stomach... When I asked Flores about the women, she put a hand to her mouth in embarrassment. 'They felt my breasts and stomach and said to me, 'You’re pregnant, aren’t you?' When I said, ‘No, I’m not,’ they said, ‘Tell us the truth! Don’t you have milk?’ When I said no, Knoygonro squirted her milk in my face, to say, ‘I do.’ ”
