PS I watched the memorial service as they removed the last piece of wreckage from the World Trade Centre, the steel beam from which the flag waved despite all that went on around it as they cleared the remains. It was very fitting. My prayers are with those who lost so much in those fateful hours, but also with those who have worked tirelessly night and day to rescue and later to recover what was possible so that there would be closure for as many of those families as possible. I can't imagine what you have experienced. My brain refuses to deal with the scope of debris, the weight on the heart, the lives that will be forever changed. May you find solace from the horror, now that there is nothing more to clear.
