Do you need to do some talking? Or do you need to do some listening? There's a point you are keen to communicate. Understandably so. It is important. Indeed, we have to ask, if it matters so much, why is it not already self-evident? Is it because you can see further than someone else. Is it because you have information that someone else is oblivious to? Perhaps a third party can help you to find some way to draw it to their attention. You can't just hold up a megaphone and shout. It's necessary to be subtle and sensitive.
