Jane: (whispers) Sierra, pay attention! Sierra: (rolls eyes) Relax, it's just a boring history lesson. Jane: We're supposed to be learning, not goofing off. Sierra: (pops bubble gum) Lighten up, Jane. School is not that serious. Jane: (frustrated) But we have a test next week! You need to study! Sierra: (smirks) I'll be fine. I always ace my exams, even without studying. Jane: (sighs) You're not taking this seriously at all. Sierra: (shrugs) Life is too short to stress about school all the time. Relax, have some fun! Jane: (muttering to herself) Fun won't help you pass your classes, Sierra.
