I don't get why Joanna didn't just apologize
I seem to keep reading excuses like "she wasn't sorry" (even read a "she doesn't have a reason to be sorry") and "it wouldn't be heartfelt anyway!" But she was going to all the trouble to be nice to the rest of the family (forget whether that was geniune or not)...why couldn't she be the same to Marni?
Yes, she was trying to be nice and pretend to not fess up around to cover up for the family, but the least she could have done was fess up and apologize when they were in a private place.
Okay, okay...it had to be this way for the sake of the storyline and comedy in the movie. I liked the movie. But it's the type of movie that makes me think later on and compare my experiences to. I know that to this day, the kids that bullied me in high school probably don't even think they ever did anything wrong and wouldn't have any intention of apologizing to me today. And I don't expect to hear apologies if I ever were to cross paths with one of them at the grocery store. But I feel like, in a situation like this, were we would be seeing eachother frequently for the rest of our lives, I would hope to sit down one day and discuss my feelings of high school with them. I would hope that even if they didn't see any wrong in their past, expressing myself, telling them how their actions and words effected me (even if they don't understand why), then that person would be able to understand that I was hurt and apologize.
As long as it wasn't some snotty "I'M SORRY!!!" coming from a 4-year-old whose parents dragged them over...I'm sure it would have been much easier to accept Joanna and lead to a friendly relationship in the future.
