Me: Should I take my trainers?
Mum: You have trainers?
Me: Yeah you saw them just yesterday.
Mum: I threw them away! They were on the throw-away pile!
Me: NO, I put them away from the pile, meaning not-throw-away.
Mum: Well... I threw them away.
Me: Oh. Fantastic.
Argh. Now no trainers for holiday.
