That means I refer you as Koishi-san (Because you seems to be older than me), right? Okay, now is this true?:


 * -chan is for younger females, and suffix for onii-chan or (maybe) onee-chan


 * -kun is for younger males


 * -san is for older peoples, and suffix for onii-san, nee-san, oji-san, etc.


 * -senpai is for seniors


 * -sama is for seniors or people with higher ranks
