There is a farmer near me who cannot read or write (OK a TINY bit but practically zero). He is worth about a million bucks and is as smart as anybody I have ever met - memory like a bank vault and fast with numbers. A heck of a nice man too. He's coming up on 80 years really soon.
I see ads like this all the time in our small town paper - it is kind of amusing I must admit. To Chili's point, there are some folks who really struggle, but I don't think this is one of those, it's too far out there.
The title of the post says it all!
