I ran into a waiter from long ago in my career and we got to talking. We remembered one instance where a family would come to brunch every week. One guest in that party, a dughter of the family in her 20's was pretty sick/anorexic looking. She would only order a bowl of crushed ice to eat. Around that bowl she would arrange crystals and some large gems and then eat the ice. The family thought nothing of it and treated it like it was normal. She got worse every week, looking thinner and thinner eating only the ice. Over the course of a few months she looked terrible. One day she was not there, the family was ther acting as usual. We later found out she starved herself to death. Very weird and sad.
