The thing is, I used to like that: feeling special because I knew something no one else did. It's a kind of power, isn't it, knowing a secret? But lately I don't like it so much, knowing this. It's not really mine to know, is it?
The narrator reflects on the feeling of having a secret that sets them apart, describing it as a form of power. In the past, knowing something others did not made them feel special and unique. However, recently, this sentiment has shifted, and they are beginning to question the value of this secret knowledge.
Now, the narrator feels discomfort with the burden of knowing something that feels like it doesn't truly belong to them. This suggests a growing awareness of the responsibilities and implications that come with possessing such knowledge, highlighting a moral dilemma about owning secrets that affect others’ lives.
