I'm not a senior, I'm only in my 30s, and I do that kind of stuff all the time. For me it's mostly forgetting to push down the lever on the toaster oven, and forgetting to turn the microwave on. The worst is when you think you turned it on and it finished when you left the room, and you take a bite of your food and it's still cold or frozen.
Oh ok well you know what I mean
Those moments of pure forgetfulness.
I did like the story about the ice cubes. Wondering what happened there to the coffee grinder.
