So I'm about 17 and 1/2 right now, my parents are going away on some vacation for their anniversary and they're forcing me to stay with my grandparents instead of letting me stay home on my own, their only reasoning is because they're saying its illegal, which is complete bullstuff as I've seen multiple instances of parents asking if its okay to let their 16-17 year old stay home on their own and not ONE person said "no its illegal" (in fact one of them apparently had their divorced mother try calling some kind of child protection service about it but they said they couldn't do anything about them staying home)
So how should I approach telling them this even, the trip is exactly a week away so I don't really have much time, I've saved a couple of links as proof but I don't really know how I should convince them that I should stay home by myself.
