" Two are better than one, because they have a good reward for their labor. For if they fall, the one will lif’ up his gellow, but woe to him that is alone when he falleth, for he hath not anthoer to help him up…Again, if two lie together then they have heat: but how can one be warm alone? And if one prevail against him, two shall withstand him, and a three-fold cord is not quickly broken. "

― John Steinbeck , The Grapes of Wrath
