How to edit social, and mood buffs.

[CottonISgood]

I want to make a mod that changes social interactions, mood and social opinion where do I start?
edit: please I need help with this an I don't know what do to.

There are like 3 different things I can think of, and that's not an area I mod 

So: be more specific in your question!  What *exactly* are you trying to do?
