Wax - I think it's mostly the latter, as I'll be glad to see the back of him by Sunday
actually I will miss him
I think there is a degree of nerves on his part but he denies it. He claims that he just doesn't know what he needs to do/get organised - but refuses to acknowledge that he is refusing to let us help ("You don't know anything"
) and we have arguments every time we try 
I went away to Uni, so I do have some experience (an East Coast Uni too so I know about the cold wind
). Dh and I both, as adults
, have some experience about what utensils are needed in an unequipped kitchen 
He's refused to engage with us, beyond a very short list he sent me (after nagging him) about the things he thinks he needs - but is now complaining that I've gone ahead (less than a week before he goes) with starting to put together some boxes with stuff for him to take. "I've not talked to him about it"
I've been trying to talk to him and don't want to be trying to get everything together the night before. So yes, I did just get started putting some things together from my own kitchen cupboards.
He's also being an arse about his finances and refuses to let us sit down with him to work out a budget. Even getting copies from him of the student loan and bursary awards (dh and I have been living off savings while we try to sort out a new direction for ourselves - but ds has never gone without maybe he should have ) so that we can understand what and when he gets his money and whether we need to subsidise him temporarily results in fights. 
At least I've managed to find out that he can pay his rent monthly - but it's up to him to fill out the paperwork and I don't know if he's done that
