My bidet toilet came with a “demonstration tool”. A (transparent) plastic contraption that can be put on the toilet which 1) activates the bum-sensor and 2) blocks the water stream.
The toilet also has a “demonstration” mode, I did not dare to turn that on, though.
I guess it shows how out of touch (old) I am that it’s completely bewildering to me that there could be people who do not understand folders … on a computer. Phones, tablets, yeah, I get that, those actively make it harder and harder to access the folder structure. But computers?
