The problem of getting in a shell is that when you emerge out of it ready to face the world, there’s no one waiting. It can get a little disorienting.
Oh no daarrling! We don’t have the time or inclination to wait up for you to work the cobwebs inside your head. There are way too many of them, love. Besides, we have enough of our own, no? So bury your head all you like, but bury it at your own risk pluzzee! And better not take it for granted that the world in general and people in particular would be waiting with a smile. Understand?
