I dunno, I don’t really get it. The comments imply it’s showing a bad example. But I don’t know any kid that would choose books over riding a bike like Harley does.
Indeed. Even 50+ years on, I’d still choose not to be trapped in a classroom!

“Outside” is not so lovely after the cops have been chasing the cyclist all over the schoolyard and tearing it up. Not to mention not so safe.
What Dvandom said. Also, you guys really don’t know any kid who’d rather stay inside reading than do physical activity outside?
As a child (or an adult) I would definitely pick staying home and reading than going outside, let alone doing physical activity outside or inside!
Okay, a good reenactment event might be better than staying home and reading.
