I realize some people will disagree with me, but to me those last few panels were just so powerful and in a way sad in how Supes didn't get that about Bats, even though they were close enough to be brothers.
While Clark doesn't buy Batman's fear act he does have a horrible record when it comes to getting Bruce (like the arc with Bekka for example he's oblivious to Bruce's affections for her and accidentally rubs it in by saying that Orion is lucky to have her).
What surprised me the most though was JLA #31 where Diana and Clark are sparring and talking about Bruce's death.
Clark -- "I just wish I'd spent more with Bruce."
Diana -- "He treasured his time with you."
Clark -- "He barely tolerated me."
Um WHAT? He comes looking for you when you're MIA or when you don't answer his calls, he's the first one to jump in when you're in danger, he doesn't let anyone else own/handle Kryptonite even though you trust them, he goes to your Pa's funeral to pay his respects (no invite necessary) and then gives you his condolences, gives you a peptalk or stern talking when you're hurting yourself, he does favors for you, allows himself to let his guard down when he's around you, He cried when you died!!
Anyway this is what Diana said to him
Diana -- "You know better, Kal. He loved you."
I think it all comes down to the fact that Bruce, even though he's a very sentimental person, doesn't like to project how he feels and can makes an image of himself that is not real but wants others to believe and Clark just plays along. Of course Clark doesn't buy the "Goddamn Batman" act or the illusion that he's an uncaring cold bastard, but maybe he feels like Bruce would rather work than take a break and spend time with him or that Superman's being a burden to him (which I think prompts Clark to not seek or engage in a personal conversation for the sake of not bothering Bruce ).
Of course Bruce probably sucks at getting Clark too (although, with the exception of Diana, he's shown that he's the first to notice when Clark is feeling down or behaving oddly) but I am pretty sure if he knew that Clark felt that Bruce didn't like him he would rectify that problem immediately.
