seeming quite cold and being quite cold as you put it are two very different things, we could all do with remembering that we don't know these guys personally, and as such only hold subjective views, as for his single minded attitude about caring for himself, well if he wants to fulfill his own potential then i see nothing wrong on just focusing on himself, moreover, what evidence do you have that affords you such moral high ground to make such an unsubstantiated claim as you do?
I don't mean it as a claim that that's the way he is. It's just how he comes across. Andy is seen as the same by many people I guess. I haven't seen enough of him to form a decent opinion though really. And like you say, we have no idea what they're like personally. I just don't really take to him from what I've seen. Can't like everyone.
