Shakespeare, Alexander Pope, Dostoyevsky have changed my life. Just as much as family.
You can loudly say “no” and I’m loudly saying “yes.”
To the extent that is arguably true (and I’d argue it mostly is not, there may be a one-way effect and/or a parasocial attachment, but “personal relationship” requires two-way interaction, and confusing a parasocial attachment for a personal relationship is the start of...lots of bad things) those relationships quite literally do not share the “you don’t choose family” aspect that applies to (a subset of) family relationships.
