Thinking of replying to their message with something like this;
Guys I'm so sorry, I didn't realise you were missing me this much? To go to the trouble you have, when you must be so busy getting ready for that big wide world out there? Look guys, it wasn't great while it lasted, but I've moved on now. I got some great people round me, hell they ain't just down the road but they're closer than you ever were. I just hope you guys can move on soon enough, I'd hate to eat up all your bandwidth and what not. Hope uni's all good guys, and remember, you're more transparent than you think! Nice life and all that?
[EDIT] Ps, Cunts.
Not bad for a first draft eh?
