i watch the way some people dart across a busy main street while others wait for the light so they can use the crosswalk ; the way some parents offer annoyed shushes to their children 's incessant chatter while others provide calm answers ; the way a group of women will sit at a coffee shop table , their eyes circulating , their words laced with critical comments , while at the next table another group sits , oblivious to anyone else and just enjoying one another 's company .
