the way I observed mine in her choice of food, how much she eats and so on can tell oredi. In the reversed, she dare not cook yet for me makan - worried that I can't swallow the taste (is it that bad? I like to Pho bo..though).. Tat's why I suggested doing trade from Vn rather than at Vn/ to Vn.
Other tots:
a) or-gui-naiz brotherhood tours to Vn, how about that? <semi exclusive tour agency>
b) frendship channel with Vn charbo <semi Friendster-like hosting.. with some small-trading between both sides..ala gift-exchange, photo-exchange,..>
Eh...how about back to the original topic? Enuf of business ventures? No one wants my IT backgrd it seems
(I go teach at their varsity maybe, and get to meet many Vn gers)
