At about 14:17 her twin (?) has a different style neck strap on her/their headgear. I have no idea what is being said or what is happening but I am curious as to her character. I remember my own experience of getting out of getting out of the car promising to keep wearing it, waving goodbye to my mother, then taking the headgear off as soon as she got out of sight and before anyone saw me wearing it, just like she did.
