Outside one of Bangkok's big malls, a local pop star appeared and prepared to perform. The crowd of kids who'd been waiting patiently in front of the stage went wild. Mobile phones and cameras were raised in the air to snap pics of the pretty pop princess. From the pedestrian bridge above, however, we were much more interested in watching the kids watching her than we were in heading down there to see who she was and how it was that she inspired such admiration. We got just as much a kick out of watching the kids' excited faces as they did from seeing their idol. Their energy was palpable. Infectious. Peoplewatching is part of travelling. We all do it. I most enjoy it with a drink in hand at a cafe on a central square somewhere, but watching people watching other people is something else.
