I thought they went to college at 19?

It's possible it was really just very coincidentally timed with the kid turning 19. But yeah, they do go at 19.
Unfortunately, the one I left alone, since I knew she would always be slow I never bothered to check if she was sick. Apparently she was. She died. Oops.

I laughed a little harder than I probably should have. The whistle smiley just gets me every single time.
