Sounds exactly like my son! He's been trained with hardly ever accidents for 2 solid months now but he still dances around when he has to go and then I ask him he says he doesn't and gets annoyed wtih me which I can understand. I spent months telling him "Tell me when you have to go potty" and now I'm telling him to when he has go. So anyway, now I don't ask I just say "let's go potty before we start this puzzle" or "when this show is over we need to go potty or the TV goes off." Sometimes it works but he doesn't have accidents so I've been letting it go. He's the one that's unconfortable and he knows what he needs to do to alleviate the discomfort and he'll go when gets too uncomfortable.
I sort of disagree with everyone who said to put a potty in the living room. I think he needs to learn to allow time to get to the bathroom. I've never done that and my son is really good about telling me early if we're out somewhere and the bathrooms may not be close by.
He also does the exact same thing with not going when he first wakes up. He still wears a pull-up at night and he does not wake up dry so I think it's normal for him to not have to go right away. He pees all night so he doesn't need to go in the morning until he starts drinking something. That's my thought. I'm not concerned about it.
