For some like me, it's not so much hating a character, as not being interested in their content, or it not making sense for Sophia. In the case of Sam, it's the basketball game in the driveway. AFAIK, groping is a technical foul and as a sports teacher, Sophia shouldn't encourage it. For Dylan, it's the choice in the prologue to take two cars or one. Taking one car is highly dangerous and illegal.
And speaking of highly illegal, same for the sex ed class. Over here, Sophia would be jailed for it, and blacklisted from ever teaching again. The nursing job would just get her sacked.
