Since
@DarkSilver now actually reads this thread now, I'll just reiterate my earlier "wishlist"
The small talk doesn't have to be big, deep convo's. Just a small couple of lines that can be generic, or tied to the state of the relationship/opportunities without the purpose of progressing it.
Ann talking a bit more about her job. Movie-watching could be a bit more randomized with the characters commenting on it. Maybe a bit more random comments about Eric leaving.
Alice could mention things about the books she reads. Reassure nothing happened with Eric, depending on the state of the relationship. Or randomized comments about Max creating a shadow when she tans. Alice and Lisa could randomly join to dry the dishes when Max offers to wash them.
Lisa could talk about things happening at school with Alex and Olivia. Or comment about the results when you are or are not helping with her homework.
Just a couple of examples. Small things, loads could be done with existing CG, so should barely increase the workload from a rendering point of view.
Ultimately I think it would help bunch with the monotonous waiting-game which occurs after most opportunities lose momentum, and you are just daily ticking the mood-elevating boxes.
