I'm talking to you.
You think I mean "you" in the generic sense of "whoever is reading this",
but I don't,
I mean you in particular.
You think I couldn't know who you are in particular,
because you think "I" am the writer of this blog post,
but I'm not.
I'm the part of your mind that is reading and processing these words,
and I'm conveying them to you,
and you alone.
