Your, Dess and a couple of other classmates are in school while the teacher is out when Catti starts making fun of Dess

Catti: well, well, well, the school freak finally quit smoking behind the bleachers and graced us with her presence.

The whole class sniggers at that remark

Catti: You're a disgrace you know that? An ugly no good disgrace. Nobody would care if you were to get hit by a truck tomorrow. And nobody will ever love you.

Hearing how she talks about your childhood friend, that girl that you were raised with, makes you sick. You get up and then go over to Dess's desk and kiss her on the mouth
