Things I don't understand about Sevilla: Part II

I don't understand...

1.  The lack of energy conservation.  They clearly don't have those commercials where dollar bills are sliding through the cracks of your doors/windows.  Today I walked by a store with four enormous, wide-open doors that allowed an intense heat wave to warm the entire street.  Same thing happens when it's hot out with the air conditioning.
2.  Why they won't build anything taller than la Giralda, a tower that was built in 1198.  I understand culture stuff, but I don't understand this.  Not even on the other side of the city???
3.  The girls that wear pants that are tight on the legs but really baggy on the crotch.  I wish I had a picture so you could understand what I don't understand about it.
4.  The metal garbages on poles that are implanted in the sidewalks.  They don't have bags and can't be removed.  I don't know how they empty them.  I guess I haven't ever done a thorough close-up investigation though.
5.  Why I take my finals and midterms on printer paper.
6.  Why my teachers pass out papers one by one instead of the take one and pass-it-down method.
7.  Why whenever I walk to the bathroom at the U of Sevilla, the girl's door is open, but the guys is shut.
8.  Umbrella tactics.
9.  How the kids at the residencia manage to eat all the nasty food that gets put on their plates.  Their plates are cleaner after they eat than when they first got them.
10.  How you can get a job as a maid working in my building if you don't know how to clean.  OR why you don't knock on my door when you're coming in...especially the bathroom door.
11.  Why the guys working downstairs start work (and the banging of hammers, jackhammers, etc) at 8AM and stop at 10AM.  Furthermore, I don't know how you get a job working with tools if it takes an average of eleven hits per nail.
12.  Why when you get McDonald's to-go (para llevar) they double cap the drink and put it in a bag inside of a bigger "grocery-style" bag.
13.  What they have against drying machines if they seem to not care about wasting energy.
14.  How there are so many beggars that are extremely talented musicians.
15.  Why they let these guys that sell chestnuts smoke out entire streets with their dense charcoal-chestnut smog.
