Musing Mondays-Talking to strangers

We were all warned as children to 'never talk to strangers', but how do you feel about book-talk with random people? When you see people reading, do you ask what it is? Do you talk to people in the book store or the library? Why or why not? What do you do if people talk to you? (question courtesy of Dena)

This is going to be short and sweet! I'm generally to shy to talk to people I don't know about anything unprompted. I'd never start a conversation myself, but I have been in the library or bookshop and had people talk to me about books. That's ok, because they've made it clear they want to talk, but I would never initiate the conversation myself. I sometimes think I miss out on stuff with this attitude, but I find it hard to be anything else.
