I have to check to make sure the stove is off even if I know I turned it off. And the lamp.. Once a couple years ago I left the oven on and left the house. We'll just say that coulda ended really badly!
After I stop pushing buttons on my celly, it goes black after a few seconds. I constantly have to push a button to light up the screen and see if I got a text. And even if I'm staring at it the whole time, I still have to push a button to make sure.
