.you must be mad, or else you wouldn't have come here

That is, if Seven didn't 'accidentally' trip Ten with his umbrella, or spill a bit of tea on him. ::slightly evil smile::
The umbrella would have been very much in-character. And then, when Ten looked at him surprised, Seven would raise his hat to him in form of greeting with the most angelic face he could muster. >:D

I feel like Six would have just sighed heavily, then just interrupted Ten in the middle of some Rose-coloured lament to talk about something else for just a FEW minutes.
Himself, most likely. *grins* Though if he was really annoyed with the conversation, he'd probably say something like, "What about Peri, Doctor? You do remember her, don't you?"

Eight might be a bit sympathetic for a bit, but finally, he'd probably just point out that all of him have experienced some sort of traumatic loss at some point & that Rose really isn't that special a case. But he'd be a gentleman about it! :D
Or he'd look at Ten while he was talking and mutter "Sam Sam Sam Sam Sam Sam Sam..." to himself until Ten got the hint and shut up. :P

Poor Susan - is she EVER mentioned in the new series? If not - that makes me mad. How 'convenient' of RTD to just ignore Susan having ever existed.
He mentioned having been a father to Rose at some point (making her look at him with a "WTF?" face) and tells Donna that he lost his family in The Doctor's Daughter, but he is yet to mention Susan by herself. *shakes head* Let's hope Moffatt corrects this.

But don't even get me started on Ten's saying WHEN SHE'S TRYING TO HELP HIM OUT, 'Rose would know what to do.' I really wanted to throw him off the bed for being so rude to her. I don't blame her annoyance with him AT all there.
I would have kicked him out. Heck, ROSE would have kicked him out.

Pretty, yes, but not nearly as fascinating as his predecessors, I would say now.
Just because an actor has a cute accent in real life doesn't make his character likeable in my books. That said, Tennant at times annoys me as much as Ten - the only exception being his story about how he met Wendy Padbury, which he narrates in the hidden commentaries from The Five Doctors.

Which reminds me - I've recently watched a YouTube video in which Padders describes how she was the agent who discovered Matt Smith, and the way she seems to fangirl him (and how much she SQUEED about him being cast as Eleven) gives me high hopes about the boy. He's got the Zoe Heriot Seal of Approval ^TM. :D
On the other hand, David Tennant freaked her out when he was a young unknown, which I think says it all.
