When Stella gives up Lollie
The part where Stella gives up her daughter for her own good - Yes, it ties the whole plot of the movie about social perception.
But, the problem I had was - isn't Lollie a bit old to where it was needed to be so dramatic? Lollie seemed like she was really close to being an adult at that point (unless I perceived her age wrong). So, if she is about to be an adult, she would probably move out to get married soon anyways. I feel it would have carried better weight if the daughter was 11-12 years old instead.
