SOCIAL
Humans need companionship because it helps with how we interact with one another. According to Rachel L. Severson, the author of this article but also a scientist, writes “Companion animals, particularly dogs, also function as social facilitators, increasing social interactions among people in public settings and in long-term care facilities.” She states that is easier for people to talk too people while they have their dog because they act like a therapeutic use to attract conversation making it easier to talk to people. This is how a companion like a dog can help socially.
In the book, Of Mice and Men, situations are quite similar when George is attracted to making conversation with Lennie whenever he finds mice.
