Cat of Khronos

I'm approaching you against the flow of time,
Yet you think I'm moving away.

I venture into the future, intruding into your line of sight,
But you won't know what I did in the past.

I bring together the moments we passed by each other,
And you believe I'm standing right in front of you.

For me, it's merely a step-by-step, down-to-earth journey,
But in your eyes, it's an elusive twinkle of stars.

You're a fish flowing with the river of time,
While I'm a bird freely soaring above the river.

I think in terms of timelines.
