Well, seeing as I work in a high school and a bookstore, yes, I talk to people/strangers about books. In fact, I am paid to do just that. I try and gauge a person’s interest by asking them just a few questions about the last book they really enjoyed. I also watch what people buy. If they purchase a stack of books and some are ones I have read enjoyed, I look at the other titles they are buying and make a mental note. I LOVE, LOVE, LOVE talking to people about books and am always open to a suggestion and feel quite satisfied with myself when I know I have made the right recommendation for a person.
If I see someone reading, I usually don’t start a conversation. I don’t really like when someone interrupts my reading, why should I do that to someone else? Plus, I don’t like to put someone on the spot in that manner. I hate when someone does that to me and either asks me my opinion on something I haven’t quite formulated yet or worse, they ruin something major for me. Usually, I just check out what book they are reading and form my own silent opinions about them based on their choice.
