Some Things That I've Noticed So Far:

1. The massive amounts of bread and starch that is eaten at every meal. Seriously, there are so many different types of carbs at EVERY single meal. For example, for breakfast, the typical breakfast is basically just toast or breakfast cookies or muffins. A lunch could be something like we just had today: leftovers of the pasta salad (with pasta, mayonnaise, tuna, oranges, raisins, walnuts and spices), rolls, mini pizza, croquettes (probably one of my favorite things so far, I can't even describe how delicious they are, but they have cheese and some type of meat inside and are fried). Although we have already eaten so many carbs just at one meal, there will still be plenty at dinner I'm sure! It seems strange that all Spaniards can be in such great shape then, which must be accounted for by all the walking they do.
2. Eggs are also another very typical ingredient in meals. For example, we had tortilla espanola the first night, and the next day for lunch we had mashed up hard boiled eggs with bread. I think that eggs may have also been in the croquettes, but I'm not entirely sure.
3. The person that cooks is usually supposed to serve everyone. Even if the plates of food are brought to the table, it is not right to serve yourself.
4. It isn't true that you can't drink the tap water.
5. Most stores really do shut down during ciesta, but stay open much later.
6. It's sometimes annoying when you are trying to speak Spanish to people and they automatically tell you they speak English.
7. People walk a lot here. On Saturday evening, we went out to see if any stores were open (very few were) and while on the streets we saw tons of people just strolling through the city; they did not seem to have anywhere to go. There were also several street performers.
8. Motocicletas, or motor bikes, are also very common here; I was talking to a few Spaniards in some bars Saturday night and they said that they are the easiest mode of transportation because you can park anywhere.
9. Most cab drivers are jerks. We had one the other night that ripped us off; we argued but he kept saying that the price was way higher than it should've been. When we got out of the car and met up with our friends in the other taxi, they said that they had paid just about half our price!
10. When guys hit on you on the streets, instead of the typical whistling you may hear in the U.S., they make a strange noise that sounds like "ch-ch".
11. They listen to way more American music than Spanish music in bars, clubs and even cabs. Older hits are also often played; for example, the other night we heard Prince and also the same Michael Jackson song in 3 different bars.
12. There is a homeless man (?) that lives on one of the main roads with his dog. He literally has a mattress and sheets, a dog dish and several other things, just beside the street. (I wonder why he is living there and how he is allowed to do that?)
13. Although I dress decently and even if I'm not speaking English on the streets, Molly and I still get stared down. We think it may be because we are blonde, but there ARE some Spanish women that are also blonde...
14. While the whole time we thought we were "locked in" to our apartment building and needed to use a key to get out, there is actually a button that you can press to get out without using your key.... all this time we thought it was a light!
    

I will add to this when I think of more :)
