Sleeping in a longhouse with a genuine ex-headhunter in the Malaysian jungle in Borneo. The English couple I met earlier that day in the jungle and since he spoke some Indonesian (somewhat similar that Malaysain) they suggested going to this non-tourist place. It is custom to bring gifts but we only had half a package of chocolate and some curly cigarettes - one of my most embarrasing travelling moments. Drinks losened up the tense atmosphere.
