A childhood belief about landscape

I think I was in first or second grade when a teacher first mentioned the idea of continental shifts, and the concept made me depressed, sad and scared.

I used to believe that someone from my family could easily get stuck on another continent, South America let's say, just as it drifted away from us on North America. I would then be separated from my brother or sister, whoever the unlucky person was to be, and never see them again. I used to get sad thinking about how much I would miss them.
