5. Hugs Are a Form of Communication
Did you ever notice how, sometimes, there simply aren’t words for the things you wish you could say? Hugs can communicate encouragement, empathy, affection, desire, happiness, and a multitude of other emotions. When friends communicate bad news or happy news, hugs are usually appropriate. When people are happy to see each other, a hug often follows. Even complete strangers may hug each other when faced with extraordinary circumstances.
