When I was in Nepal after college, I visited the Chitwan Jungle. Our guide told us, "If you see a rhinoceros and it charges, climb a tree." In retrospect, I really should have asked a few follow-up questions such as "What kind of tree?," "Can we practice?," or "How often does this happen?" But I didn't ask any questions. We walked through the jungle and came upon a large rhinoceros, at which point we stopped and took pictures. I stepped forward, took another picture, and stepped forward again. And then the rhino charged.
