common sense "aint" common

I have a hard time understanding how some people can be SO book smart... and very clearly intelligent...but be lacking in the common sense area.

And even when you try to get them to see things the way they are in real life, they still don't get it.
Perhaps they never will.

Sometimes I feel like I am wasting my energy for nothing.

And yet, I still try.

Talking to a wall, much?

Sigh.
