The Middle Ground...

Sometimes we fall into a vicious cycle of repetitive argumentative and/or annoying discussion with someone who seems to misunderstand or don't get at all what you're trying to say.

If that's the case, I'd say I'm pretty sure that the other doesn't really understand what you're trying to say even if you so believe that you've done extra miles to try to explain your side.

When you notice that you're becoming victim or perpetrator of this wasteful endeavor. Stop. Breath. Think. Breath again.

Chances are you are talking about something under some unspoken assumptions.

Like trying to describe a duck to someone who's thinking you're talking about a pig.

Don't assume. Ask, elaborate... and do so calmly.
