Its having to get up before noon thats the true problem, they just live in a different timezone
Now I’m 40 and I still am more functional after 10am than any time before that. And I’ve worked jobs starting at 4am-6am for months but never quite got used to it
I used to fall asleep standing in the shower. Do not miss it in the slightest. Every day is a good day to not be in high school.
