I wonder how much thought the original inventor of the power socket put into his design. If he was a little bit—just a little bit—cautious, he could have been flipped the shape of the ground plug (the mouth) upside down, so that this cute family won’t be having surprises: they would be smiling instead.
Imagine each time we plug a power cable into the wall socket, we are greeted by a smily face instead of a sad one. Wouldn’t have that improved our lives tremendously? We would have been greeted by smiles for several times a day.
