Serious Trait (Reupload) by Zerbu at Mod The Sims

The Serious trait has the following effects…
Sims will not suffer from low Fun until they drop into the extreme levels, and even then, they only get a +2 Bored moodlet.
Sims will gain all mental skills slightly faster.
Sims will gain most social skills (as most related to jokes and pranks) slower, with the exception of Charisma, which they will gain slightly faster.
Sims will get an Energized moodlet from a day at work that would be boring to other Sims.
Playful emotional auras will emit a Bored moodlet instead.
