How to Tell a Child is a Reader

At the beginning of the summer, my daughter's most-anticipated activity of the summer was reading. She didn't have to put a book down and go to class or do homework. She could simply enjoy as many stories as she could squeeze in. And she squeezed in a lot. I'm not sure how many hours she got this summer because she lost track around day three. But my son kept track of his reading log for a contest we'd entered and he logged 7,307 minutes (over 121 hours).
​Don't worry. We did more than read this summer. But we did burn through quite a few stories and make multiple trips (per week) to the library.

The thing about readers is, you can usually tell when you're talking to one. Even if they don't tell you.
For instance, my daughter usually has a book in hand. As well as one on the dining table, one on the couch, one in her bed, and several others scattered here and there. She uses whatever is nearby for her bookmarks. The other day I spotted a marker, a headband, and a kleenex all shoved between pages so she could pick up where she left off.
That's an obvious way to spot a reader. But there are other more subtle hints too. For instance, my daughter has taken to calling things "horrid." When was the last time you heard that word used? Not necessarily a normal fourth-grade-girl word, right? And yet, she loves it. She also pronounces some words in a way that shows she learned it by reading and not by hearing it. Trust me. We've had to decipher quite a few words over the last few years as she slaughters the pronunciation. But that's okay. Because she usually uses in the right context.
Also, most of my daughter's conversations will eventually end up in a discussion of various characters. She just can't help herself. She falls in love with the fictional worlds she reads about (and who can blame her? I do the same thing). Those characters, to her, are like friends. So, they come up in conversation.
