One if the most enjoyable moments in our explorations of the villages along the Mekong was a visit to a school in Chong Koh outside Phnom Penh. The cruise line takes a collection from each group of passengers to support weekly English lessons since that’s a skill that leads to better employment. So we arrived in time to help them with their dialogues. Our guide who is a former teacher led us in a clapping/name-recognition game.
I lost and my penalty was to dance or sing. You can guess which one I chose so I led a group rendition of "If you're happy and you know it".
We all left smiling.
