Question. Let's say you have a point-of-view character who is lying to himself. Example:
Tony grew up in a vagabond family, and never put down roots. Now he's grown and he's chosen his own path of stability. He bought a home, keeps the same job for years, even drinks at the same pub every Saturday evening. He's as settled as they come.
But his brother comes into town and suggests a grand adventure, "like the ones Mom and Dad used to take us on," taking a couple months to hike the entire Grand Canyon. Tony would probably have to quit work, but so what?
Now how would you do a scene where Tony tells himself and his brother that an adventure is the last thing he wants? He marshals all sorts of good reasons he can't join bro, and they're good reasons. But underneath, he so wants to go. Really. The old vagabond spirit has been reawakened. But he knows his life is here in Podunkville, and he wants to want it. He doesn't want to want to run off with his brother for adventure.
So... how would you show him-- internally and in dialogue-- saying that of course he can't go vagabonding, that his life is here, that he doesn't WANT to leave, that he's never been happier, that of course he's not bored, that he's not that rootless wanderer anymore and has no desire to return to that life.
And how, within that, would you let the reader know (if not Tony) that he really is itching to go with his brother, that part of him longs for adventure, that he's at least partly lying to himself when he says he's no longer a vagabond even at heart?
That is, how do you show what he thinks is the truth, while letting the reader know it's at least partly self-deception?
I mean in first-person or deep third point of view, no omniscient.
