Shes been through this a couple of times it seems, parents drop her off she starts getting along with the people there but then she has to say goodbye and move on to repeating everything again new people, new environment, new rules, kids seek affection of their family figures and its really hard getting into a new school were everyone already has friend groups and youre not a social madman a la Najim, i can understand that somewhat my family moved a lot and i was in like 9 different schools in my childhood at least my parents were always there though.
Yes she has shitty parents and if you want to have a kid you need to make sure you're ready to be them for them at all times at the very least till theyre like 15 and they enter highschool.
