Wait, What? (All in a day's work)

A girl and her mother checked out a stack of books, including Waiting for Normal.

"I don't know about that one," the mother said. "I might have to read it first."

"I've read it," I volunteered. "How old is your daughter?"

"Ten," she replied.

I nodded. "I think it'd be okay." (She'd just returned Robin Brande's Fat Cat, for heaven's sake.) Then, considering that I was talking to a Concerned Parent, I added, "There is a gay character."

"Oh, I don't care about that." (Emphatically.) "Just about other stuff that 10-year-olds should not be reading."

...um, assuming she's talking boy-girl stuff here? Isn't the issue of sexual identity fairly... sexual?
