For the safety of your children and infants // pour la securité de vos enfants et bébés.
Your from the 12th century. Stop. Think. Why are you even on a plane? what is a plane? That chainmail will only make you drown faster even if the smell of rust does make the baby sleepy. You don’t have planes. Go home, crusader. Put that baby back where you found it, in the same state you found it in.
Once I was on a plane, and my brain was about to start leaking out of my ears with boredom. (That, and I wasn’t at all looking forward to the next six hours I’d have to spend waiting / travelling.) So that nonsense was the result.
