I hate telling people what my sign is because apparently my sign is like the reigning asshole of the zodiac or something.
You're a Sagittarius?
yes, i believe in the Zodiac. you know why? because it's fun. I was out with some friends once and we were talking signs, and I bet them that the girl across the room was a Cancer (like me). Sure enough she was!
Okay back to the topic:
My only advice is that you have a bit of leeway in regards to a person's interests. Some dudes can't get over the fact that a girl likes different music or books than them, which can be problematic.
For me, I'm just intrigued when a person has a passion for ANYTHING (well, mostly). It's a great opportunity to learn about new things, and about that person.
