this one's a bit of a tough one. i'm trying to think of things that are of value to me.
i don't tend to have any heirlooms or objects with a history, but there are some things i really cherish.
there's my copy of house of leaves by mark z danielewski, which i got from barnes & noble the same day i went to watch spiderman: across the spiderverse. that day was great, because i got to see a really good movie and then get a really good book.
by the way, you should read house of leaves sometimes. it's really good and half of it is in the formatting. it's formatted like an essay about a film, but the film in question doesn't exist, so you're learning the plot of this film entirely through reading this essay as things slowly break down, both in the story of the movie and the minds of the writer and the editor.
that's the only object i can think of that has affected me in some way. i guess maybe my computer but there's nothing to say about it other than the internet being responsible for who i am today, the object itself matters less than what it accesses.
