Number Three.

I'm not the most sociable guy, I don't go out unless there's no one else around to do it for me. In my group of friends I'm the only otaku however I also have similar intrest to them I keep my otaku thoughts for when I'm online and my more sociably acceptable thoughts for when I'm around my friends.

Who says she has to be intrested in everything you do? Of course having similar intrest helps strengthen the relationship but being total opposites gives you a wider view on other people's thoughts and oppinions.
