Last night, my roommate came out into the living room where this friend and I were studying. She had gone to bed earlier but due to stress from her job, couldn't sleep, "I'm kind of having a panic attack."
Our friend went and got some scotcheroos he had made the night before, and we sat with her until she was calm. He still didn't say much.
As it turns out, when it comes to being a friend, words are optional.
