I just wondered if anyone else was having their sims with a constant sad mood while on holiday at the snowy escape world There is no explanation why , it just says sad all the time
Traits should also influence the shared sadness - an evil sim would enjoy someone being sad, a mean sim would likely pick on someone for being sad. And as for the getting sad about not being good at something - a hot headed or perfectionist sim would likely get angry that they can't do something well. So, as usual, traits mean nothing.
