Is a phone call an act of aggression? The answer is it depends.

The latest digital trend recommends texting before calling someone and it's a dividing people based on their communication preferences.

Diane Gottsman is the founder of the Protocol School of Texas. She coaches professionals across the county on modern etiquette which often comes down to communication styles.

"My best advice is to read the room," Diane says. 

Not sure how your boss wants to communicate with you? Ask.

But what about the rest of us? Is it really bad to call a friend who crossed your mind? What about a friend who rapid-fires text missives like they're wiffle balls?

It's a digital minefield out there!
