Rosie "When Will visited me here once they let him in my room, which was weird because they don't let boys in the boarding house. So I felt special, but then they came in and he had to leave. Turns out they thought he was my brother, not my boyfriend, so they let him in. Fail."
Rosie "Biggest fail ever AND on way out girl who I know's mum came in and was like "OH ROSIE. IS THIS YOUR BROTHER? YOU LOOK SO MUCH ALIKE!". And awkward turtle was done"
