Once Stained, Then Fade

I don’t understand where you have gone.
The friend I once knew seems to be following a different song.
Your interests seem to have changed from kindness to physical gain.
Did the microchip of others’ influence finally make its mark or stain?
That deep stain of the hubris of one;
when all the people are gone is the show really done?
Is this eyeliner guilt, security, or shade?
All I know is that your memory seems to fade.
