HK, I understand your annoyance with your friend b/c she was making many assumptions. However, I also understand why she may have made those assumptions. Many of us (black people) get our jobs and move as far away from black people as we can and never look back or try to aid the community from when they came. I don't think that it's absolutely necessary to live among blacks (although I will b/c when I go to work in the mornings, I want black children to see a young black professional and know that they too can do that), I do think that it is essential to continue to take part in the struggle.
Don't be mad at her. Maybe she didn't mean any harm.
