In the quote from "This House is Haunted" by John Boyne, the speaker reflects on how familiarity can lead to a loss of awareness. They suggest that over time, people tend to stop noticing the things they see every day, whether it's ordinary objects or loved ones. This phenomenon highlights how routine can dull our perception of important aspects of life, making us take them for granted.

The quote emphasizes the subtle change in awareness that occurs as familiarity grows. It conveys the idea that, without intentional attention, even meaningful relationships and familiar surroundings can become background elements, losing their significance in daily life.
