A symbiotic relationship exists between George and Lennie, and is demonstrated throughout the novel, Of Mice and Men.
Lennie is almost moved to hysterics and his fear does not quickly abate. Lennie could not take care of his rabbits or even survive without George.
The emotional symbiosis between George and Lennie helps each man. Lennie's attachment to George is most strongly visible when Crooks suggests George is not coming back.
Explanation:
Since these characters do not have symbiotic relationships, they cannot experience life to its fullest and they have trouble leading a healthy, and rewarding life.
