Cliff loves driving buses for very different reasons from all of the other drivers whom Rachel has met so far. For the rest, their primary motivation is serving or connecting with others, and actually operating the vehicle is secondary. But for Cliff, it’s the other way around.

She wonders how to balance her empathy for Beth with her empathy for all the people who have to deal with Beth on a day-to-day basis. Unfortunately, as with most of her dilemmas, there’s still no clear answer—Rachel still doesn’t have the “guide to being a good sister.”
