how did i live without this information

I’m one of those annoying people who thinks way too much into fantasy shit. Like I know it’s not real but I’ll question everything about the story/movie. Like how do foreign demigods get into the US without visas and just live inside of the camps without the government finding out? What do the parents of demigods tell their family members when their kid is at camp and they die? What are the parents told if they’re like Piper’s dad and they don’t know about the gods, when their child dies? How did Thalia go to school with Annabeth without any transcripts or any important information? Same thing with Annabeth, how did she attend school? I have so many questions about the Lotus Casino I won’t even get into but you get the gist. I’m just one of those people who questions literally every aspect of a story. It’s annoying really.
