person A: I just started this new book about the American Revolution. It's not something I usually read about_comma_ so I hope it's good.
person B: That's cool_comma_ I'm not too familiar with it myself.  Is it pretty interesting so far?
person A: So far it is. I really think it's going to be a great book.
person B: It's always nice to get lost in a good book.  One of my favorite hobbies.
