Extroverts and Introverts in Sims?

This is a little bit anuseful, but it would make the game more realistic. Just if you could choose to make your sim an extrovert or an introvert would be good, or not choosing at all. Because almost always when you play the Sims 4 and create a sim the only way to make your sim seem a little bit more introverted is to give them the loner trait or just make them live in isolation alone, and I don't think these are the best ways. Or if you want to make your sim seem extroverted you just make them talk to npc because npc don't almost never even try to talk back, and that makes my sim seem like the worlds one and only yapper the yappington king of the yapping land. Or is there a way to make my sim an introvert or an extrovert whiteout mods???????
