"I guess it'll take a little time for them to get used to the changes in me.Everybody seems to be frightened of me." "People don't talk to me much anymore or kid around the way they used to.It makes the job kind of lonely" pg.232 After charlie got the operation everyone didn't want to be around him.So if charlie hadn't changed himself he would be very popular.
"Them changes.I don't know. You used to be a good,dependable,ordinary man- not too bright maybe,but honest.Who knows what you've done to yourself to get so smart all of a sudden.Like everybody around here's been saying,Charlie,it's not right."After the operation Charlie was "not right." The workers had fired him with a petition 840 workers agreed to it.So changing himself was a bad idea.Because people started to dislike him.
Every action has a consequence

"This intelligence has driven a wedge between the all the people i once knew and loved" pg 235 This shows that his decision to be smart put a "wedge" (consequence) his loved ones,and friends.
