This evening wife and I were sitting down to cards, easy child 1 playing Webkins on the computer and difficult child down in the basement. The water alarm on the sump pit went off: the washing machine had started pumping out, the sewer line was backed up, and waste water was coming up from the floor drain. wife and I ran down and shut off the washer. difficult child was in the bathroom down there, burst into tears and ran past us upstairs and outside on the porch in her pajamas in the snow. wife went up and coaxed her back in. She confessed that she has been purging -- making herself vomit -- for the past three weeks. It took us an hour or more to clean up and disinfect the basement. She kept saying "I'm so sorry. I'm so sorry." I can't even begin to imagine how badly she must feel. I feel so sorry for her. It is amazing that we missed it yet again. In retrospect you can clearly see that she was eating much more than usual but not gaining any weight, but somehow we were blind while it was happening. She has become expert at hiding it.
