What things in the Sims 4 do you find odd and wonder if they are intended?

I totally forgot something else in my first post here, the fact that sims, when eating together and I want them to talk, stand up, hug each other, don't sit down again and talk. I always need to tell them manually to sit down again. I wonder if this is a bug or really intended. Who in real life would stand up and hug their parent just because they want to talk?
