Don't be guilted into the parent's emotional blackmail. If they are concerned about him then they need to send him money either to go back to NZ or to subsidise him while he lives in UK. He is their responsibility and if he is becoming depressed then he needs to be back with people who care, his family not you. Obviously he misses your home cooked meals, full fridge and laundry service all gratis. Who wouldn't? His London and Newcastle "friends" don't supply this so naturally he wants to be back in your warm and cosy nest. The suggestion to send an e-mail to him, copied to his parents outlining in no uncertain terms he can't come back to your home and the UK is not really the place for him with the recession, high rents and Winter all happening etc. is really good. Not being direct will just make him and his parents keep contacting you.
National treasures. Who would you choose?
