We have a sister who is a spoiled entitaled brat and a brother who is an obsessive freak. I don't like them but I do pity them. After reading many reddit stories and one of things I came to realise that these tropes are the making of their upbringing by their parents spoiling them.
Who'd decked out their room with hundreds of the same photo? Stupid. At least make them different or just make a single shrine with that image in the middle.
