Intelligent or Smart?

When they’re wrong, it’s intelligent to know,
But it’s likely smart not to tell them so.
With this you may not totally agree --
Often I wish this was a rule for me.

Falstaff says that valor needs discretion;
He preferred very passive aggression.
If nobody noticed, that would be fine;
He still knew without his butt on the line.

Should you keep your opinions to yourself;
Just bundle them and set them on the shelf?
Who needs the benefit of your learning
When it’s their beliefs you’re overturning?

Well, you may say some things are worth the fight.
Sometimes someone must set what’s wrong to right.
Perhaps that someone sometimes should be me,
But when, I would bet. you would not agree.
