Maybe House was lying to Cameron...? I'm really not sure. I think I might rewatch those episodes.

I think that when House's father was abusing him, he didn't believe it was abuse, but instead punishment worthy of the lies he believed House did. The kind of things that John House did were the sort of things that are used to discipline people in the army, which is probably where House Sr. learned them. Since he believed he was doing a justice, he probably thought that people didn't really need to stick their noses into it, and if he just never mentioned it and kept it a secret, then technically he's not lying.

Alright now this opinion is coming from a high school student, so don't take anything to much to heart.

House's dad was in the millitary and seems to be the stereotypical army dad who insists on strict moral conduct in his house. By never lying I think House means his father never allowed lying in his household, among with other things, and would instill harsh punishment on House if he broke one of those rules (the abuse). House's father may have never considered it abuse, if you understand some of the training the millitary once had to go through you would understand that that is bordering on abuse, actually it is abuse in a lot of cases. House's dad may have just seen it as a way to break his son of his bad habits. So he may not have ever lied, he may never had mentioned it at parties, why would you need to, but I'm sure if someone directly questioned him about his treatment of his son he would not lie, never thinking he had done any wrong.
