Hiding behind the Broom

It is also shown when Chief hides himself from other people, particularly McMurphy when he says " And I leaned over and go to mopping with my back to him so he won't see me grin. I feel good, seeing McMurphy get that black boy's goat like not many men could" (91). I feel that this expresses how Chief feels about McMurphy and that he is afraid to show him that he likes McMurphy and that he's happy with him. In this passage he is physically hiding behind his broom but metaphorically he is hiding his true feelings for McMurphy.
