Proper

Proper is a social trait introduced with The Sims 3: Supernatural and The Sims 4: Snowy Escape.

The Sims 3: Supernatural
This trait conflicts with the slob and inappropriate traits and is first available as a teen. ''Proper etiquette has quite become a thing of the past. Luckily, Proper Sims still remember the old ways and conduct themselves by a code of honor. Or at least a code of nice manners...''
