Not exactly! I mean, it's not like you have to memorize the person and the term ... it depends on the situation! Like, if I want a favour, I call Mouri 'Mouri-san!' or 'Mouri-sama!' but when I talk about him to other people I call him 'Mouri-jisan' or 'Mouri-jichan' if I'm talking to his daughter. But when I'm talking with my friends he's just 'Occhan' and if he heard me use that, he'd scold me.
