Did I turn it off?
The iron, the oven, the stove, the hair-straightener, the humidifier, the electric blanket – on or off?
1. Have rules about unplugging things – this full-process is easier to recall
2. Have a safety list to check
3. Never iron in the morning
4. Never leave the electric blanket on once you are in bed
5. Like picking the keys up – always do a physical check
Find out what works for you because the feeling that you left something on is not a great one!
