There was no newspaper, I told him; at some point, it disbanded from lack of interest. I can still picture my brother in the doorway of my bedroom: I longed to return to whatever I was reading (\u201cA Tree Grows in Brooklyn\u201d? \u201cThe Clan of the Cave Bear\u201d?), but he stood there for what felt like an eternity, lecturing me about the decline of democracy without a free press, and the apathy of my classmates; the high school <em class=\"css-2fg4z9 e1gzwzxm0\">had<\/em> to have a newspaper, and if no one else was going to revive it, he insisted, then I must.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">I can only imagine how I would have responded had my parents given the same lecture: probably not at all.

They didn\u2019t have particularly strong feelings about our high school newspaper or whether we should have one, and maybe they didn\u2019t know me the way my brother knew me. Parents, I sometimes think, forever see their children as fixed, essentially unchanged from who they were when they first entered the world \u2014 as, say, a fussy baby or overeager toddler. I was the youngest of three, passive, a watcher more than a doer, someone who had to learn to talk fast because if I didn\u2019t, I\u2019d never get a word in edgewise at dinner.
