What are the two reasons Kenny thinks he would be made fun of if it wasn't for being related to Byron?

Rufus is the new kid at school, the object of mockery from the other students by virtue of his ragged clothing and strong Southern accent—but Kenny thinks he's a godsend because now the other kids will have someone else to pick on instead of him. However, Kenny's feelings soon change after the teacher sits Rufus right next to him in class. Kenny's miffed because he's sure that the other kids will think that he and Rufus are friends, which will make them both the object of merciless teasing.
However, Kenny really has no need to worry. As the super-cool Byron's kid brother, Kenny pretty much gets a pass, despite his close proximity to Rufus. He also doesn't get picked on despite his being incredibly smart and popular with the teachers—schoolchildren hate a teacher's pet—and the fact that he has a lazy eye. Ordinarily, one or both of these would be enough to make Kenny's life an absolute misery, but because he's Byron's brother, he's left alone.
