Thanks for great reporting, I especially enjoyed the Cambodian family perspective.
I am not looking to retire permanently in SE Asia, but both Thailand and Cambodia are strong candidates for places where I would like to spend 2-3 months a year in a not too distant future. I love Bangkok, but other parts of Thailand that I have visited so far, have not made the same impact. In Cambodia, I loved all the places I visited, except perhaps for Sihuanukville, but I was just there for one night.
