How do I improve my statements instead of asking questions?

Ive been trying to use statements instead of asking questions but they always seem to endup with getting a yes or no answer.

For example, At a book store i'd open with 'hey you seem to be into reading books a lot' Her: 'no' Me: 'what are you into then?' Her: 'why?'

Another example Me: you must be listening to rock music Her: no

You see where i'm going. I understand sometimes some people just don't want to be bothered with. I just want to know is there anything I could do to improve my statements instead of asking questions and come off as annoying.
