i was like 16 or 17 or 18 or something (i don't remember) when harry potter became a thing, which is the age you avoid things like that.
if i was an immature 15 year old, i could have maybe gotten into it, and if i had kids in my 20s, i could have found myself reading it to them. but, 16-18 is the age where you tend to avoid "children's books" pretty viciously.
i was also the kid that looked towards the older people in the room and really didn't like the younger people. so, i was the last gen xer, even then; i was interested in underground 80s rock music, and trying to build friendships with people in their 20s, rather than trying to connect with people my own age. even at the age of 20, about the year 2000, i realized i was dealing with a generation gap, or on the cusp of something, with people that were almost the same age as me. i'd go work on projects with kids in my class, and realize i related better to their parents than i did to them.
but, i had a handful of friends that were outcasts and rejects, and they tended to prefer the company of people younger than them. so, i remember hearing people talk about it. i never interpreted it as anything more than a children's story, and never developed an interest in it. i'm not exaggerating - i never even cracked one of them open.
even as a kid, i went for the classics. i wanted something more profound, and had no interest in literature for young people that just struck me as a waste of time. so, i was reading like joyce and asimov and stuff, rather than rl kline or whatever else the kids in my class were into.
the closest thing to a contemporary popular novelist that i ever got into was stephen king (by 1995-1996, i had read pretty much everything he'd written up to that point) and i was well aware that nobody my age was reading him.
so, i vaguely even know who she is, and i haven't the remotest interest in her opinion, at all.
