GraphQL,
you're intuitive and flexible,
we'll be friends
I know beginnings,
I know endings too,
and life-in-death, and something else
I'd rather not recall just now.
First encounter
We met in an unbelievable year,
When the world's strength was at an ebb
I marvel at everything as if it were new.

}Forgive me that I ignored the sun
And that I lived in sorrow.
