During the part that Michael, Sonny, Tom, Clemenza and Tessio are sitting in the Don's office and discussing how to take out Solozzo, Sonny says that Michael should go with a couple of guys to Luca Brasi's house, then Tom says: "Maybe we shoulden't get Mike involved too directly"." Sonny says: "You're right. Mike hang around answer the phone, be a big help, huh." Michael felt ashamed, and he could see that Clemenza and Tessio diden't like him at all. Is it true that they diden't like Michael? Earlier in the novel it mentions that Clemenza took care of Michael when Vito had no time and gave him gifts, and later (I haven't finished the novel yet.) in the movie Tessio says: "Tell Michael it was strictly business, I have always liked him." Did Clemenza and Tessio like Michael or diden't they like him?
