Summer Sales, Popcorn, & I'm Terrible At Spanish Social Norms

I want one of these so badly. Their eyes move back and
forth as the second hand ticks. It makes me happy...

So, the woman that I sat next to on the plane down here (like 283 years ago) told me that sales begin in July. I didn't really think that they began July 1st, but oh, they do.
In a huge way.
It's apparently going to be like Black Friday everyday for 2(?) weeks. It's just ridiculous. Every major store is absolutely packed and they all have fairly decent sales, not life changing, but still good. The lines to the cash register and to the changing rooms are just obscene. I feel like there's at least 40 people inline for the changing room. At this point I'd rather just assume it fits, and then return it if it doesn't. Even if I have to go through the return in Spanish.
Furthermore, in my exploration, I found a cool little clothing boutique  I decided to look it up before going in and I learned that is actually the clothing made by an underground dance/funk/rap record label. Like what. So, I think I'm going to investigate that later on in the week, it seem pretty interesting.

Also, I found a place that I can buy popcorn. Everything is going to be okay now.
I've had this life or death craving for the past two weeks, but I finally managed to get some. Just some good salty and buttery popcorn.


Another thing, my host mother has asked "our" neighbor's daughter if she wanted to help me with Spanish for the next week or two, so today my host mother and her mother introduced us. I didn't realize that the mother was french, which makes her (the mother's) Spanish VERY difficult for me to understand because of her French accent. I also learned that the daughter speaks French to her mother and Catalan to her father and Spanish the rest of the time. That blows my mind. Someone can speak that many languages and it's not even interesting to these people, it's just normal. She does not have a french accent, whew, because that would just add another level to an already difficult conversation.
To complicate things further, I'm still not entirely comfortable with the greetings in this country. I'm not entriely sure what happens when two men meet each other (literally everyone I've met has been a girl, kind of weird now that I think about it), but when two girls meet each other and most of the time/some of the time when a guy and a girl meet each other  they're suppose to do the kiss on both cheeks thing. This always throws me for a loop because older women don't do this, but the younger ones seem to, so I'm always standing there (super awkwardly may I add) while I try to figure out what they want me to do.
This time is/was especially funny (and awkward for me) because I just stood there, completely unaware of what I should do, until she started to step forward, so I thought "Okay, normal handshake."
Nope. Like half a second after I decided to commit on the handshake, she went for the cheek kiss. I realized this a little late and in return got a very weak/lame handshake until I realized that she was trying to do that cheek thing and then I was able to correct myself.
Gosh. Make it easy for me please. With Spanish social norms, I need all the help I can get.
After that debacle was over with, we tried to coordinate when we would meet.
(Just a note, whenever I meet someone new in Spain, I can't fully understand them until I get used to their particular accent, this case was no different.)
At first, I assumed that they were asking when I was busy (so they could figure out when I free), but then I realized that they were asking the opposite. After stumbling around trying to understand what they were saying and after formulating some "sentences", I think that we're supposed to meet tomorrow at six. Even with that I'm not 100% sure and I"m also not sure as to who is suppose to come to who's door (we live right next door to each other. Normally this wouldn't be a big deal, but everyone seem to make a big deal out of it....
As usual, I have no idea as to what I'm doing and no idea as to what I'm getting myself into.
