Annotation of page 124

Like several other pages, 124 is filled with justification as well as honesty from Humbert. In the second line, he says, "I was still resolved to pursue my policy of sparing her purity by operating only in the stealth of night." This is one of Humbert's ways of justifying his actions and protecting himself from guilt through the use of the cloak of night. As long as it's nighttime, that makes what he's doing with Lolita alright.
In the middle of the page, he goes on to justify his urges through talking about history and past cultures' life styles. "The whole point is that the old link between the adult world and the child world has been completely severed nowadays by new customs and new laws." He has proof through history so that is part of his defense in making it okay.
Calling himself a therapist, sensualist, and moralist toward the end of the page shows more of his inner conflict as well as trying to justify his actions.
The last two lines shows a part of why Humbert has a fetish for little girls. "I should have understood that Lolita had already proved to be something quite different than Annabel. Annabel was his first love, and he lost that love at a very young age and he his trying to find that connection again.
