I don't mind it all. Just don't try to get me into it or start forcing me to sit next to you and hear your manga "stories".
All I ask is, if I say "No thank you" or "I'm not interested" then please respect that. Just like I'll give you the respect to tell you politely I am not interested or whatever have you, then show me that same respect.
I have met one during high school. It was bad, I mean really bad (I may be exaggerating but this is the first time I've met someone that was hardcore into it. Maybe not hardcore but it was up their). It was bad to the point when we would wait for the school bus, she would pull out her manga and start showing me or others. If I tried to walk away or sit somewhere else (on the bus) she would follow me until she finishes her story telling. Even when she finished explaining the story she would put me on the spot by asking me what I think. I didn't wanna say anything to hurt her feelings (:/). This girl either was a Fujoshi or just an attention whore. Whatever she was, and I hate to sound like this but, she made me think that all Fujoshi's are like her. I haven't seen her much, don't know if she is still into that thing or not but yeah. (Do apologize for being narrowed minded with Fujoshis but with the problems this girl gave me, I was just fucking annoyed with it.)
