To end loneliness, you need other people plus something else. You also need to feel you are sharing something with the other person or the group that is meaningful to both of you. You have to be in it together and it can be anything that you both think has meaning and value . . . A one way relationship can’t cure loneliness. Only two way or more relationships can do that. Loneliness isn’t the physical absence of other people. It’s the sense that you’re not sharing anything that matters with anyone else.

- John Cacioppo, scientist of loneliness
