Sad, I wonder why the neighbors don't know each other better. We found that organizing block parties was a wonderful way to meet people who have moved in and share with them experiences and stories. Our neighborhood has gone from probably 95% white to now 30% Indian, 40% Chinese, and some Russian and probably the rest typical western european decended whites. Through out that as people move out and people move in we try to make people feel welcome and they really do appreciate it.
