surgeons have nothing on the thoroughness of a four year old washing her hands!
Sweet lord, I know! 4 yr olds take FOREVER to do EVERYTHING. Just watch a preK classroom having lunch, those kids can drag it out for HOURS because they are so busy chatting, telling stories, and yucking it up they forget to EAT. (and they know that when lunch is over it's time to go potty and take a nap....)
