“Out of the mouths of babes.”
In a scene from the movie Slingblade, all the “geniuses” are baffled by a lawnmower that won’t start. Low functioning Carl’s initial observation reveals there is no gas in the tank.
Let me share a personal true story along the same lines...
I have been in the automotive service industry all my life and have owned several shops. One day many years back I heard this load clatter coming down the street towards my shop. I knew right away it was someone driving on just a rim after the tire was gone. The guy pulled in and we made a deal and I went to work on it.
As he was waiting he kept muttering to himself and shaking his head. Being an open kind of guy I asked him if everything was OK? He explained that he was mad at himself for not being able to understand the directions on the sticker on the trunk lid about how to change his own spare and ruining the rim by driving on it. “they make no sense... I couldn’t figure out how to do it”.
So trying to make him feel better I told him that anymore very few people have actually changed a tire or know how. I told him I see it all the time. I told him that I have met many very intelligent people who couldn’t figure out how to do it either so I wouldn’t let it bother me, kinda normal.
He busted up laughing to himself, so I had to ask what he found was so funny. He said “you are not going to believe this... but I work for JPL... I am currently working on the mars rover project”. All I could say at that point was “well then... maybe you are right”. lol
