Face it, Emoji is here to stay. Texting is visual, and images can enhance how we talk. But, will it also change the content of what we say to each other?

In this intimate episode, one couple banishes all written words from text messages for a month to see how it alters their emotional vocabulary. Along the way they are forced to create their own lexicon of imagery -- oddly, not terribly unlike ancient Egyptians and Sumerians. Naturally, this 21st century couple hits a few comical communications mishaps as they build a visual language of two. At the end of the experiment, Emoji-only texting seems to morph from a guinea pig gimmick into a profound lesson in what is often missing from the written word: nuanced emotion. 

Grocery shopping though gets way harder.
