War over. Wife no longer nag or talk about the lens. Time to move on and concentrate on capturing good photos.
We need different approach for different people. I understands my wife's style so I choose to let her find out rather than tell her what I want to buy.
Some wifes may be different. come on, we all behaves differently too. There is no right or wrong approach. we must apply the right approach to the right person. If I discuss with my wife that I want to buy a $2K+++ lens, she will stare at me and you will actuallt see a a sign saying "DONT YOU DARE" on her eyes. But if buy first talk later, den will only get some remarks like "so rich".
