It is hurtful to call someone overweight.
Josh's coworker Steve is a fat guy who loves to eat more than his fair share of the office's donuts every day.
Josh wants to tell Steve to stop eating so many donuts.
Josh suggests to Steve that it would be fairer to his colleagues is Steve only had a couple donuts every day.
Josh tells Steve he needs to stop eating so many donuts because he's morbidly obese.
Steve realizes he was being selfish and vows to be more considerate with his allotment of donuts in the future.
Steve is deeply embarrassed and develops an eating disorder, fasting for days at a time.
