Natalie blushed self-consciously at hearing Sarah's question, not really sure how to answer it.  She took a bite of her burger, to give herself time to come up with something that was still true, but that was neutral.  If Erik wanted to bring it up, that was fine, but she wasn't sure how he'd feel about her mentioning their topic of conversation to the whole group.  Talking with one person about what you were into was one thing, but some people who were perfectly fine discussing anything and everything on an individual basis were shy when it came to a group.  She didn't know Erik's personality all that well just yet, and she didn't want to make him uncomfortable.<br/><br/>"Not much, really," she answered her friend after a minute.  "Just talking about some of our hobbies," she added casually, which was true, but it also gave Erik an out if he didn't want to into the details.
