But who taught you that self-education and knowledge were important pursuits in life?? Sure, your parents might not have 'explicitly' demanded this of you, but we all know Asian parents stress education, grades, studying etc. more than the average American parents (and moreso than average Southern parents--that's NOT just a stereotype!) I'm going to make another assumption so don't shoot me--but I think both of you are full-blooded Asians, and not mixed blood like Heidi.
You really should stop making assumptions. Just because parents instill in their child the importance of education, doesn't mean it's the same as self-enlightenment or discovery. My parents thought that history, culture, philosophy, and religion were the most worthless classes. They didn't encourage me to take those, and infact tried to dissuade me and get me more into mathematics and science.
In her mind, she comes from whatever American town she grew up in, and her foster parents and their family are her background.
Nobody is denying her of this, or against it. But should she have completely forgotten about her past, and was she really that stupid to go to Vietnam completely clueless as to what it's like? Hell, even though i haven't been there, i know it's a 3rd world country and the rural can be extremely backwards. And if i was to go visit there, i would certainly try to learn more about it.
Freaking out at how long it took to go shopping? Freaking out when they asked her for some money to take care of her OWN mother? Alright, she didn't raise her, but she sacrificed giving her up so she could live a better life, and she completely forgets all that? Do you realize how far $50 USD a month can go in Vietnam? Is it that much of a sacrifice for her? You would expect there would be more patience with one another, but no, she freaks out just going to the market. She left when she was 6 years old... she must remember some things about her childhood.
