Kind of reminds me of DSMOS...
people = teeth
This reminds me of the Oracle protocol and how it embeds a poem. A common thought is that this was done so that any reverse engineering would run afoul of copyright law.
https://noss.github.io/2009/04/28/reverse-engineering-oracle-protocol.html
How odd. The poem appears to come from a self-published book from a semi-obscure poetry tumblr: https://books.google.com/books?id=zLtCBgAAQBAJ&pg=PA49&lpg=PA49&dq=erin+hanson+the+day+I+lost+my+very+first+tooth&source=bl&ots=dB7ktGZBVK&sig=ACfU3U1C6CaP4O9crqBJ9SOMH4-2xTIU5w&hl=en&sa=X&ved=2ahUKEwi11dy51uTsAhVtl3IEHdmPDQQ4ChDoATAGegQIARAC#v=onepage&q=erin%20hanson%20the%20day%20I%20lost%20my%20very%20first%20tooth&f=false
