and that's the truth about people

And that's the truth about people, that they leave you without even noticing.
I knew that people don't listen, and don't look at you carefully, and that they say things without thinking about it that break your heart into many little pieces.
But this was new to me, and I discovered it just recently, that people just walk away, and leave you alone, and never come back, and they don't. Even. Fucking. Notice.
