Shy

Shy is a trait that will be released with The Sims 3: Late Night expansion pack. At the present time, it is unknown what attributes the trait will have, whether the trait will conflict with any other traits, or which pre-created Sims in the expansion pack (if any) have the trait. The trait may be similar to a removed trait called shy, which was merged with the Loner trait. Its existence was confirmed during a Grant Rodiek Twitter session regarding the new expansion pack.
