T - sounds like a great phone call. Just don't read too much in to it (but to me it sounds like he's missing you all).
And will the resume be an AOS that he will appreciate? Or am I letting my crazymaker get to me again? I think even if AOS isn't his LL he's going to appreciate your help with his resume. Besides, it's a nice thing to do and it makes you feel better doing something nice for him. Right? So don't expect anything in return and do it if you really want to.
