(Emily is standing in front of her open locker, in the busy locker room. Markus approaches behind her.)
Markus: Hey Emily! I saw you and your mum at the supermarket the other day. I would have said hi, but...
Emily: That wasn't my mum.
Markus: What?
Emily: That was my aunt. I don't live with my parents.
(She walks away, frowning, leaving Markus standing dispirited.)
