Yes. Literally, they were bouncing off the walls. Some walls were damaged. Some kids were damaged. The younger ones in all classes were wackier than troop of crack-smoking monkeys today. I think it had to do with the warm weather – at least 15C, breezy and springy. I'm not sure how much English they learned today – I focused on synonyms of "crazy."
Sophia tried to sell me some "magic shampoo" that would make me "look younger" – I'm wondering if this was some kind of hint regarding my appearance. She said it was $400 per bottle, but said it would also cause me to grow a handsome beard instantly. I told her it sounded kind of dangerous, and asked what sort of chemicals were in it. She didn't know about the chemicals, but said it was perfectly safe. I decided not to make an immediate purchase.
