when an artist wants to show you their art
or a writer wants you to read what they’ve written
it’s quite often an expression of trust
because a poem or a story or a painting are often things that come from the heart
little pieces of the artists themselves
and if they’re willing to share it with you
you should appreciate it
True facts here.
Edit: I guess I’d also like to add, that the artist also likely trusts your taste. That you can give a proper critique. I would never ask someone that primarily reads erotic, urban fantasy to read my sci-fi horror. That way madness lies.
