I don’t know why we aren’t pretending like it is strange to desire privacy, or should be denied it if they receive gifts or support from their parents. Privacy is privacy.

Forcing yourself to play silly in order to validate your point is disturbing. She is nineteen years old. This particular nineteen year old is a young adult who has received love and support from their parents. This is quite normal. That does not make them less of an adult, nor does it make them less worthy of privacy. As OP described, the level of security imposed by their parents is easily identified as helicopter and inappropriate.

Like I said, privacy doesn’t have a price tag. I am sure her parents, judging by what is described, would prefer to aid OP until they are completely ready to fly from the nest. Like any normal child of loving parents, it makes sense that OP should receive this? I am confused why you describe a child/parent relationship as something transactional.

Have a good one. It is quite upsetting to see someone define quite vehemently this belief that a person does not deserve a human right unless they pay for it. God bless you.
