Winter

This is you! Your name is Winter, and you're 15. Today, your Mum gets a call from your school (you decide why but if bad it eventually gets better). You are Winter, however you start off as the teacher calling his/your Mum (you can specify this by saying for example "Hello, is this Winter's Mum?" the teacher asks) and then switch to Winter after when he/you get/s home (you can specify this by saying 'Winter arrives home from school' or 'I, Winter, arrive home from school')
