When I was in school at least once per year we had to do “duck and cover” earthquake emergency drills.
Now, to think kids in Mexico are using “duck and cover” to dodge bullets.

It is absolutely amazing to see a kindergarten teacher preventing all children from panicking and turning this situation into a normal class activity, such so that the kids are all singing, while just outside their school five people are being executed.

Translation:
Yes, sweetie, everyone on the floor. Little ones… what? What, sweetheart? No, nothing’s happening love, just put your little faces on the floor… with your… sweeties, put your little faces on the floor. Nothing is the matter, nothing is going to happen to us, just don’t get up please. We are going to sing a song! We’re going to sing… I know which one! Yes! If rain drops were made of chocolate, I would love to be there… Who wants chocolate!?
