Bo---I know some immigrant families in which the parents do not speak English at all, at first, I was amazed. How could they survive in this society if they do not know the language. However, they seem to be living a good life, they depend totally on their kids to interpret for them. And their kids used the language skills they learnt at school to help with the bills, grocery shopping, etc. Yes, sometimes, they do greater things than we think, however, I still think it is meaningful if they could go for a field trip with their peers just to enjoy the time with their friends.
