Make sure you say good night it's important

Where ever you are, know the culture's stunted
In a petri dish, go down for seconds
You
You know what you are
But that could always change
Didn't you count on that?
Someday faraway came and gone while you were in the living room
So
Live it up
While you still can
The updates are great
But only call to say goodbye
So
Goodbye
And have a nice life
Better than how I left it
Please
How did I leave it
Confused, right?
No, better.
But I'm afraid of whatever it used to be
What is it now?
