One prominent badge of fieldworkers, distinguishing them from the natives, restless or not, is their asking stupid questions. Nigel Barley, as ever, has a good illustration (The innocent anthropologist, p.41):

“What happens to a man’s powers/soul/spirit after he dies?” I tried querulously, like a vicar hoping to get a current affairs discussion going at a youth club. They ignored me. Then one young man turned round and snapped, “How should I know? Am I God?”

Among many posts on fieldwork exchanges, note Bruce Jackson’s fine exposition, and Speaking from the heart.
