Check your clothes dryers for lint. See what condition your electrical cords are in. If you burn wood, look around the stove or furnace and see if there are combustibles nearby. Many times when you bank the fire for the nighttime period, the stove itself may glow. I remember this from when I was young.
Some people like to see the stove get red hot.
Nothing to play with, my friend. Since people have started to burn wood, you hear about chimney fires happening too often. Clean the chimney. Candles need a lot of attention. It s so easy to leave the house and forget to put the candles out.
