Crazy Ngrandma scheme to control grand daughter. Tldr: don't believe N's lies about how they will financial help you.

Sandy (Ngrandma) declares that the next time her grandchildren come over she's going to reiterate the house rules, point out the two rules plaques she already has up, and put up another ten. The other members cheer her on. Much later, her granddaughter chooses a university she would need to drive to, instead of getting a ride with her mother. Sandy demands to have input into her granddaughter's school choice before she'll hand over the promised money. One of the commenters escalates with a proposed plan of action so long that it spans two screens. The gist of it is that Sandy is correct to take a hard line with her entitled "pissant of a GD," and should give her granddaughter the money only if the girl agrees to get a technical or nursing degree and presents her GPA to Sandy for approval. Sandy should keep the money in her own name, refuse to pay for books and supplies in order to keep her granddaughter frugal, and send funds directly to the school rather than allowing any to pass through her granddaughter's hands. It's an extraordinary demonstration of punitive control over a girl who insists upon choosing her own university. The other members agree that it's an excellent scheme, and Sandy resolves to put it into action.
