We all do/say something to find out the truths from our children. Reading about the blue dot on the forehead made me wonder what tactics everyone else uses to find out the truth in whatever incident. The past several months I've been using the science of fingerprinting. Generally all I need to do to elicit an "I did it" is get a ziploc baggie. Rarely do I need to actually place the item in question in the baggie. Sometimes just the comment of going to get a baggie is enough to have them chasing after me spilling the beans.
