On asphalt roads, strangers throw water bombs at each other whenever they encounter someone around the corner. Squirt guns are everywhere. Some even use sprinklers or water hoses, small and big, to spray water in all directions. These people are from all walks of life. They are all in different clothing, some wearing swimming goggles, in raincoats or in swimsuits. Others do not even bother to change their clothes at all. They just wear their everyday attire.
