I came across this problem last Sunday when talking to my brother and mother. We were in the car, my brother in the back seat, and me and Mother in the front...
Bro. : "So, Mom, what are you reading at the moment?"
Me : Um... She's driving?
Mom(didn't hear me) : "I'm reading Agatha Christie. The Murder of Roger Ackroyd."
In this conversation, my Mom understood my brother to mean the book she is reading, but hasn't finished, while I understood it as "right now." Is there another way of phrasing it concisely without having to resort to something like:
"So, Mom, what are you reading at present, not at this exact moment, but the book that you haven't finish yet?"
Ideas please?
