I have never been one to double check things like locking doors and turning of lights etc! I must be the most boring soul in the universe to not have such a quirk of nature! I just guess that I was raised to do thongs only once! I hate it when someone asks or tells me something over and over,as it makes me feel as though they do not trust that I have listened to them properly the first time!
Me too Finy. Yezrs ago our home had a very elaborate alarm system and you had to set it and then you had about 2 minutes to get out the door before you activated it. When you arrived home, the first one in had to deactivate the alarm.
Well I would set the alarm, leave the house, and then think to myself "did I actually press the set button". It became such a chore, that I insisted that we just deactivate and ignore the (very expensive) alarm system. Hopeless.
I do that sort of trick with many appliances around the house.
I'll often be at the end of the driveway (walking) or halfway down the street when I just can't remember if I turned the computer off or not. Sometimes i don't bother returning to check, but upon returning home have found it was off, or it was on and in sleep mode so I thought it was off.
