My friend greeted me warmly and dragged me into the thickest part of the crowd. As we walked, the people passing by threw water at us and we responded by firing shots from our water pistols. As we weaved in and out of the crowd shooting water at people and chasing those who tried to get away, I suddenly realised I was having fun. The smiles and laughter of everyone around me were infectious, and the Thai people seemed genuinely pleased that I was joining in. Above all else, we had been given permission to behave like children, and the urge to forget our troubles and simply play was very strong.
