Lennie & George-
These two travel together, have been for years. They are the best example of polar opposites working together. They rely on each other for the not-so-simple task of survival.
Candy & His Dog-
Candy has had his dog for years, since the thing was just a pup. They are inseparable. Candy always mentions how his dog used to be this great herding dog, but now it has a sliver of life left in it. They neither really seem to hugely benefit except for the idea of loneliness.
Overall- Lennie and George and Candy and his old dog are similar. Both relationships are respected by the partnership and have lasted for several years. Both work or have worked side by side for these years and share mutual feelings, at least for the most part. They both seem to be made up of a “dumb” and a “smart”, a “big” and a “small”, an “irresponsible” and a “reasonable”. Both partnerships seem to be something in which if one were to go, the other wouldn’t know what to do or how to move on.
