Another reader in foreign parts gets our bumper box of Dubble bars this week. Dawit Hailu is headteacher of a new English-medium kindergarten in Addis Ababa called English Alive. "Luxuries are few and far between," he writes, "and most of the children have never tasted chocolate, let alone had a whole bar to themselves." Take it a chunk at a time is Friday's advice.
If your class deserves a treat, email firstname.lastname@example.org to tell us why, giving the name of your school and marking your message Dubble offer. For information on fair trade, go to www.dubble.co.uk.
