Actually, "-sama" is used in regular conversation; go to a store in Japan and they greet you as "customer-sama." "-chan" is used for men all the time, too; it's just the Western perception that it's only for little girls.
"-shi" isn't really used in conversation. Ever. It's something you see more in the newspaper.
It seems like you are very upset over Japanese suffixes, Brody. ):
Yea, well, he was kind of dumb. And Vriska's character is interesting, but... I'm very conflicted about her. If she had, like, killed Sollux I would have liked because there is literally nothing I don't about her except for the fact that she abuses and then offs Tavros. I mean, she uses dice, I'M SO INTO THAT.
Also, who is your favorite guardian? I like Rose's mom for some reason, I think it's the scarf which I was sad Jack didn't take. :I
Vriska. Well, because I like Tavros, I kind of dislike her for all that biz. But at the same time, she loves Nick Cage, and I also do (albeit ironically). She does have her moments, but she's too mean to Tavros so I have to say I don't like her. >::::[
