Monday: Mary walks into the girls' change rooms at school and finds two girls drinking alcohol combined with Monster and Redbull. Mary wants to tell an adult, but instead, the girls pressure her into drinking as well.
Tuesday: Mary vomits in the morning and stays home from school. She misses her PDH class that day, but asks her friend Pheobe to send her the notes from the lesson.
Wednesday: Pheobe is away from school, so Mary is unprepared for her PDH exam in Period 3. She feels upset throughout the day but doesn't feel like she has anyone to talk to.
Thursday: After school, the girls that Mary saw in the change rooms tell Mary that they can trick the worker at the liquor store into believing that they are overage. Mary tells them that she believes them, but they pressure her into coming along to see.
Friday: Mary stays at home and drinks alcohol that the girls gave her on Thursday. She feels sick and upset, but can't stop herself. She absent-mindedly invites a lot of people from her school over for a party.
Saturday: Mary can't remember what happened on Friday night. Her mum comes home from a work trip and Mary tells her everything. Mary's mum is disappointed but helps Mary recover.
