Lynn's Comments: This was a scenario from home. My daughter, Katie, had, at the age of four, learned how to use a screwdriver, and had gone about my mother-in-law's house unscrewing things. Ruth tried to open a kitchen cupboard door and it came off in her hands along with the handle. We were both perplexed. How in the world had all the screws come loose? We looked about for Katie and found her outside in the driveway trying to take the license plates off my car!
