Read the passage.

in the 1960s, a study was done at the university of california, los angles (ucla). it was determined that only 7 percent of communication is based on the written or voiced word. fifty-five percent is based on body language, and 38 percent is based on the tone of voice. real communication doesn’t come from reading someone’s words on a screen. it comes from hearing the person’s voice and the tone in which they say things. seeing the look in their eyes, their gestures, facial expressions, and body language provide additional cues to their meaning. true friends have a physical connection. they cry on each other’s shoulders and hug each other with affection. when they hear exciting news, they grasp hands and jump up and down. so if we try to forge new friendships or maintain existing ones based on digital media only, our nonverbal cues disappear. the use of abbreviations, a few quick words, and emoticons may not truly convey what we want to say. and they may not provide the kind of comfort or emotion that our friends need to hear.
