Do you read several books at once? I have one by my bed, one downstairs for "free time" (never happens) and one on my desktop.
My parents used to function that way. In fact, if you left any reading material anywhere near my mother or my father, you would find them an hour later, reading a Nancy Drew novel, the Mnemo - Neur volume of the Encyclopedia Britannica, or the newspaper lining the inside of a drawer.
Naturally, reading came very naturally to me, and I was called a good reader in school. But I'm not a good reader. I'm a bad reader; this means that if I start in on something, like my parents, you'll find me frozen to the spot an hour later. And if you say my name while I"m in the throes of a good book, I won't hear you, probably. Reading, for me, is a vice.
Writing is the same way. Today I'm working on a sequel to The Night Watchman express http://www.amazon.com/The-Night-Watchman-Express-ebook/dp/B004Q3RT7E/ref=ntt_at_ep_dpt_1 as well as continuing a Christmas story for kids, editing my first novel over for possible publication, reading / editing a wonderful book by my friend Trin Denise...
It's a schizoid way to live. But that's just me.
