I don't know if you remember that, but before The Sims 4 was released, producers said that Sims could be either left or right-handed. And it atcually worked, but I remember that it was only for eating and drinking.
Now I noticed in my game that Sims which have the left-handed hidden trait are eating with the right hand, when it was supposed to be on the left one.
Also, all the other interactions that could have handedness variations are only made with the right hand.
Probably most of the people won't care about it as only 10% of people are left-handed (including me), but I would love if left-handed Sims could eat and drink with the left hand, and more interactions made with the left hand.
