This is driving me crazy. I have my kids doing something, like homework or playing chess and those idiot adults interrupt them for a chat. I have searched for a long time and the only mods for chat ...
I usually keep my sims busy so I haven’t really noticed this much or maybe it’s just one of the few things in this game that doesn’t bother me, I do love it when my sims socialise with each other. Mind you anything is preferred over them just standing around doing nothing, I hate that.
