Never overslept in them, except one time on accident. I had a friend also doing it, and we would nap at different times and check in on each other to make sure the other person woke up. So I’d go to sleep with my ringer on and text him when I was waking up, and if I didn’t, then he’d call me.
I like this perspective. Next question I would ask, then, is should more thought get put into which language someone chooses from the onset? And I agree about cultural perspective over business, but even still, what makes French so valuable proportionally to all other languages taught (given % that learn French to % that speak French)
