This is sad story with the loss of unsupervised children which is common here.
We have children swimming in the klong behind my house and About two years ago I cold hear a young child crying and found two in the water clinging to the edge, one about 2 years old and pulled them out. We took them to the community head with the story with my wife complaining about the situation of children swimming there. I did not get a thank you for saving the children or the parents come to the house. My wife is angry as the children still swim there.
They need to educate communities and schools of the dangers of entering water if they cannot swim.
