describe the relationship between george and lennie. why did the boss and others find it so unusual

George has to look out for Lennie and take care of him.Two grown men who somewhat love each other as brothers do.

the two men were like brothers. They were very close and also very distant in likelihood. Lennie was retarded yet hard working . Although they had a brotherly relationship , lennie sought george as a paternal role model . He did as george said and he asked for permission to do what he wanted himself. George and Lennie are very close.
