This person sitting next to you tells you their life story- you listen so as to not be rude.
They go on about their plans
For the future; every one has plans.
And you scream, "It's all so redundant!"
You go on to say "what we want can never be achieved in this mortal form."
Try explaining a rocketship to a sloth.
Your dreams are too big to even make sense
So everyone thinks your crazy,
But they are insane.
"We're already dead, can't you see?" You tell them.
"Our dying breath lasts over 50 years.
Exploring our cell doesn't mean we are free. Don't you want to be more than a tax attorney?"
You plead, hoping somebody can offer some sense- anything, a nod of acceptance. All you're met with is silence and bewildered eyes.
You break down and cry at this feeling of lonliness.

But really
You say nothing.
You just sit there
Listening so as to not seem rude.
