I wonder how long some of those making comments here have lived in Thailand? Many of the parents of children tragically drowned here are both workers on construction sites and farms. Their children are with them and of course wander off. Most Thais I suspect, cannot swim. I taught all my nieces and nephews to swim at an early age. Of course the kids wander off and some come to harm. A lack of parental control? Again, of course. A reservoir being dug, being fenced off? You must be joking. This is not a Western country where rules and regulations are in abundance. This is Thailand. R.I.P. little one.
