There would be folks who would do it because they just did not know any better or plain and simple, lacked common sense. Common sense seems to be lacking these days in many walks of life. I live in the south where they are waving their confederate flags, STILL, fighting the civil war.
Just received word that a friend of the family's son lost his home to a fire. Without power in the northeast, he left a fire burning in the fireplace unattended and went upstairs to sleep. He was awakened at midnight by the smoke alarm and a fire downstairs.
No one was hurt, but again, is it not common sense to never leave a fire unattended?
Better to check everyone than b sorry. Since your child is little it should b no big deal. My kids are 5and 9, I talked to them prior, and let them know they could b checked to make sure all is safe and to avoid bad guys, it should b no problem
