In Milan Kundera's book "Immortality," the author reflects on the complexities of human relationships and the often-unexplained reasons behind our behaviors toward others. He suggests that our interactions can be misunderstood or even harassing, driven by personal perceptions and emotions that remain opaque to us and those around us. We often view others through a distorted lens, which complicates our understanding and connection with them.

The quote emphasizes the struggle individuals face in reconciling their internal selves with how they are perceived by others. Despite our attempts to make sense of ourselves and our relationships, we often find that our self-image leads to more questions than answers. This self-examination hints at the universal human experience of feeling like a puzzle and grappling with the weight of others' perceptions in our lives.
