hey, as a Bulgarian and as a person who spent 12 years in Bulgarian schools this story is soo realistic and funny!!! Though it happened to me hundrets of times it is great to understand the "native speaker's" point of view.
The cheer leaders appeared in the recent years and I have never thought that they dance on county music. Ours always dance on electronic music!!
by the way, we consider it good luck when it rains on the first school day, nobody minds it. Even when you leave home, the parents always spill water on the ground and you have to pass throuh the wet puddle!
Regarding the alcohol and the teachers, wait to see the part with the students, then draw conclusions... ;)))) as you know, in Bulgaria alcohol is allowed to be drank everywhere and obviously, at any time, so it is no problem to get it. The same applies for the cigarettes. You just will get used to it and will start not to notice it.
