in the past, I have left the crock pot running while out, but I don't like to, and haven't done so in a very long time. I never leave the house with the dryer or dishwasher running.

A few years ago, a house just up the street from my daughter's school burned down. It happened to be owned by one of the teachers, so we all heard the full story. Her nephew, who went to college nearby, stopped in to do his laundry, and left a load running in the dryer while he went back to class. They lost the entire house. All she had time for was to run in, let out the dog and grab some photo albums. Her children were still in the school at that time. Can you imagine looking from your school playground and seeing your house burning down, or later the shell of what was left?
