  • Typical teasing:
    • "Aw, my baby sister looking for her bra? That's so weird... are you sure you didn't just misplace it?"
    • "Go ahead, tell Mom and Dad your sweet big sister is being mean. It's your word against mine, Muffin."
    • "Dumplings, you kissed me first, remember? Don't act like a victim now."

SEXUAL PROFILE
