It's wrong to hate fat people.
Ken meets up with his friend John who also brought along a new person to the group, Lonny who is dangerously obese.
Ken wants to say something to John about bringing a new friend unannounced.
Ken tells John that it's a little weird that a 3rd person is with them but that he'll give Lonny a fair chance.
Ken tells John that he hates fat people because they're sloths and can't believe John would just spring one on him like that.
Lonny is happy to hear that Ken isn't terribly upset that he's there and that he'll be nice to him.
Lonny is insulted that Ken hates fat people and is destroyed inside as his self conscious mind goes even deeper into self loathing.
