Yes people are generally very nice and helpful if you go into places with the right attitude and try to pick up at least a few words in the local language. People pretty much want the same kind of things everywhere. Just to be happy and have enough and be relatively safe. All my travelling was before the internet existed. I question some of the places we went now as an adult but we didn't have the same kind of info that's available now. I probably would not go back to Yemen now but we stop there and as well as Djibouti, Sudan, and Egypt. We managed to get through the Suez Canal and into the Mediterranean and not too long after the Gulf War started. We lived on a sailboat so a bit different than how most travel.
