(You're Charlie)

Alastor was with the other staff member, them arguing because they kept messing up when suddenly, Alastor fell asleep on the sofa and Charlie(you) being Charlie(you) made this a trusting exercise to not wake up Alastor or else... she put a blanket over Alastor so he could sleep. five hours later, Alastor woke up and saw a note on the table, written by Charlie(you). He was upset because nobody ever saw him asleep, so they would never let him live this down.
