I offer you a solution: meet the people who live around you! What better way to reconnect as a society and alleviate those safety issues. Heck, once you get to know your neighbors, your safety will improve. Imagine two, four, six or more additional pairs of eyes keeping a lookout for suspicious activity. Your kids are "bored"? How easy is it to send them next door to find out if the neighbor's child can play for a bit.
I know my neighbors. My son has spent hours playing with the boy next door who is near his age. The elderly couple across the street is always happy to visit and let you know if something suspicious has happened in the neighborhood and the retired police officer who lives diagonally from me is not only a source of security, he has been known to mow our lawn when we go on vacation!
Am I glad I know my neighbors? Absolutely. Do I feel better about the street I live on because I know some of the people who share it with me? You bet. Am I going to start making jello molds for a block party? Well, probably not, but you never know. Stranger things have happened!
