The quote "You can draw the blinds in a brothel, but people still know what you're doing" from Iain M. Banks' novel "Inversions" suggests that one can attempt to hide their actions or intentions, but ultimately, the awareness of others cannot be completely obscured. It reflects the idea that certain behaviors or situations, regardless of how discreetly they are conducted, will be evident to those around us. The metaphor of a brothel implies that certain activities carry inherent social perceptions.

This notion holds significance beyond its literal context, relating to broader themes of privacy, morality, and societal judgment. By drawing blinds, one may seek to shield themselves from scrutiny, yet the knowledge of their actions often permeates through the veil of secrecy. This highlights the tension between personal choice and public perception, emphasizing that some truths are difficult to conceal, no matter how much one tries.
