different ways to snort snot

The white man, a colonialist, sipped a gin and topic. His manservant, an indigene, stood patiently awaiting orders. "You know," said the colonialist to the indigene, "you blacks have got some dirty habits. I will never understand how you people can just snort your snot onto the ground, and keep on walking." And we will never understand, thought the indigene, how you white men can snort your snot into little square cloths of white linen, which you keep in your pockets and use again and again and again.
