I'm an MIT graduate and spent 50 years working in electronics and computers. My wife and kids think I'm not smart enough to be the village idiot. They set out one day to buy a computer --- spent a huge amount on an old, outdated, used computer. About a year later, when the shortcomings were obvious even to them, they bought another one, this time new. Then the new one had to go back for various fixes and upgrades, none of which really worked. I was informed the other day, that it's time for a new computer.
Any suggestion that I be consulted before the purchase is always met with the universal response: "you just don't understand Thailand".
I guess I don't.
