if you are here, you must have found a thing in a book.
or perhaps elsewhere, maybe it slipped between the pages,
fell to the floor,
blew out a door,
napped in a gutter,
did something to travel beyond where it was placed. (little traveller in the known world of unknowns)
no matter where you found it, the fact is you found it.
love it, lick it, give it away, trash it, light it on fire, do as you please.
do what you want/need to do.
