Will I be able to build good friendship with another otaku?

Depends on how anda act on it...I dunno If I should answer this since I'm also a bit socially-akward (and sejak that I mean I always keep people in between: not too close,not too distant ^^"...)but anda know...do a private cosplay show,play some Anime related games,watch Anime together...y'know,those kinds of stuff. Haha...I'm giving bad advice, but seriously though, just let time do its course. anda already found some common ground so make that a conversation topic from time to time (not always because it would become kinda pushy)and if anda really are committed then,I'm sure your efforts will be rewarded.

I know exactly how anda feel,and quite frankly,I suck since I don't even do much about it,but when I do,my confidence in socializing and stuff gets a tiny bit higher...It's like letting bottled up feelings out because then you'll realize that anda have the inner blabbermouth inside of you. ^^"

The same thing also happened with me . I met a girl who was an otaku like me And didn't know how to become her friend. But we started talking hours about Anime and Anime related stuff. We also started watching Anime together. Now we are best friends! anda can talk with her about Anime and the characters. anda can give her some gifts with a picture of her favourite character(I did it,once.) atau buy some Anime dvds for her. invite her over your house to watch anime. start Singing Anime theme songs together :) me and my friend keep doing this all the time.
