It is seriously misnamed isn't it? Not common at all. And intelligence doesn't have a great deal to do with it either.
I do think intelligence and common sense are two different things. I've known very intelligent people who can't cope well with every day life where common sense is needed.
I'm past the wondering stage, I'm heading towards desperately hoping.
I feel we must never give up hope, no matter how desperate that hope is.
There is an old saying: common sense is not very common.
