Other mistake: 'Lottie and Evie sat cross legged on my bed' but the story is from Lottie's point of view so it should say Amber and Evie.
Character mistake: It says 'Evie and Lottie said they tried to come round earlier but no-one answered'. It's supposed to be Evie and Amber, as it's Megan talking to Lottie.
