10.2 Social Interactions
--------------------------------------------------------------------------------

Social Interaction are all the interaction that happen between two Sims. There
are three types of interactions here, User Directed, Non-User Directed and ones
that can be both. The following tables will only be dealing with interactions
that are User Directed, as these are the important one, beside, you don't want
your Sim to do too much without you.

  Note - There are some Social Interactions that can only be used if the both
         Sims are using the same object.

These tables have been split into groups by main interaction options. All baby
and Toddler interaction are dealt with in Section  10.2.1

  Note - These values work in an and/or relationship from what I can tell,
         so if one match and the other does not, it may not work.
