That is really hard.. I do hope that you and your family are gonna be able to go back to Cambodia... In the next few months. I am pretty sure the world is slowly opening up. Malaysia plans to open borders in December.
So each water truck that comes is paid by the landlord? But it's good that you are positively handling every obstacle that comes. Hardships make life better once we get back to greener pastures.
I'm not sure who's paying for the water delivery, but it looked like to me a private truck hired by the state, because there 2 government workers along for the ride with the privately owned truck. I assume this delivery was free because the state has failed to provide so many people with water not living next to the road.
Luckily for the government people far from the road are usually poor, Guyanese, Cuban, or Haitian, and are not of great importance politically. I am hoping 2022 is a year of opening borders, and it would be really cool to spend New Year's together as a family somewhere in SE Asia, but I sense it will take a little longer than that.
