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

Depends on how toi act on it...I dunno If I should answer this since I'm also a bit socially-akward (and par that I mean I always keep people in between: not too close,not too distant ^^"...)but toi know...do a private cosplay show,play some animé related games,watch animé together...y'know,those kinds of stuff. Haha...I'm giving bad advice, but seriously though, just let time do its course. toi 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 toi really are committed then,I'm sure your efforts will be rewarded.

I know exactly how toi 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 toi 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 animé and animé related stuff. We also started watching animé together. Now we are best friends! toi can talk with her about animé and the characters. toi can give her some gifts with a picture of her favourite character(I did it,once.) ou buy some animé dvds for her. invite her over your house to watch anime. start chant animé theme songs together :) me and my friend keep doing this all the time.
