Things I found confusing as an Immigrant to the US

When I first came here from Honduras to the US here are the things that I couldn't understand

1. I was young so I didn't understand that one could actually OWN land. I thought that the world belonged to everyone. I thought the Earth was our home. So it blew my mind when I realized that people fight wars for pieces of land and can claim it theirs by putting a stick into the ground.
2. I grew up with very limited food, no refrigeration, or oil so I was frightened when I went to the supermarket for the first time. What sorcery was this? They had fruits and vegetables I've never seen before, and food came in pretty boxes and cans. I'd never seen so much food in one place and for the first time I could pick what I wanted to eat instead of eating what we had.
3. Where I come from all children must be vaccinated. In North America people have a choice. But North Americans are afraid WE bring diseases. 
4. In my language you can pretty much sound out words and spell them correctly. Not English. It has rules and tricks. I gave up trying to understand them all and just accepted  it. For example this sentence: The farm was used to produce produce. Produce has two meaning now. :/ Eggplant doesn't contain egg. Pineapple is used to describe a fruit but it contains the word pine and apple in it. I was annoyed with "I before E except after C" rule. I can't even sound words out most of the time. Words that sound like they begin with "f" start with ph instead. There are silent k's and words that sound like they start with k but actually use c instead. There are silent G and hidden vowels you have to account for. I'm used to it. But in the beginning I cried when I did spelling tests.
5. The idea of "need" confused me. In the US you need certain cloths, or technology to fit in. There's an obsession with desire, shopping and owning things. That I had difficulty understanding. People will tell me they NEED McDonald's because they are STARVING. "If I don't get that purse I will DIE". 
6. The obsession with dieting and restricting food. I thought with everything the US had and the more that it always wanted that this was a strange paradox. To have so much but to want to appear to have so little. With so much around you why would they choose to not have what others in the world can't have? I didn't understand how a country with so much power and stuff could suffer from so much low self esteem. We don't hear about depression or eating disorder where I'm from.
7. New York was place I would never think could exist. I thought the bridge would fall at the weight of our car and us in it. It didn't. I kept staring at the sky scrapers wondering where they ended, and what kept them up. I wondered if they could touch heaven. 
8. Chapstick. When I first came here I was suffering from lips so dry they were bleeding. But I thought this was normal, that's life you know? My dad bought me my first chapstick. And it was life changing. And it smelled of strawberries. I kept applying it and used it up in a week. And so began my chapstick obsession.
9. Shampoo. When I came here I had a lot of dandruff and I had lice. I thought this was normal. I took showers in my country but I used water that I got from buckets from a nearby waterfall and nothing else. So when my mom made me shower and put this horrible stuff that got in my eyes and made me cry, I fought with her. I grew up to like it though. I liked it so much I named my first teddy bear after shampoo. But during the time I couldn't pronounce Shampoo. So his name is Champoono. 
10. Peanut Allergies. I never knew a nut could kill you. Hearing my fellow classmates cry about their experiences going to the hospital because they smelled a nut made my eyes widen. I never heard of such a thing because where I come from peanut allergies don't exist. 
11. I couldn't believe when I got here that I could get water directly from my home whenever I wanted it. And that you can buy water in containers. 
12. Soda really scared me. It was like nothing I ever experienced before. There was no words to describe it. There was no natural food I could compare it to because it's made from chemicals but it tasted so good. That's what fascinated me about food here, a lot of it is made up food that is supposed to taste strange but addicting. 
13. I grew up in the US since I was five but I realized after a few years that when people were talking about "those" people, immigrants, and "aliens" they were talking about me. Being young I was flattered by the term "alien". I was obsessed with documentaries about aliens and wanted to be abducted by aliens. I thought I was superior for being part of the "alien race". I thought "They're  just jealous because they're  not from space". Invader Zim was my favorite show. I thought since North Americans said I was an alien I must REALLY be an alien and I thought that was really cool.
14. Nobody goes outside. People stay home all day. I tried socializing with the other kids when I went to school but I found out quickly that it wasn't cool. Everyone is insanely independent here. In my culture we take the time to help out neighbors and strangers and we always, no matter where we are, take the time to socialize before and after every event. In the US as soon as classes end people go to their separate activities and they don't stay and chat. I kept wondering where are these people going?? It was really bizarre to me that people could stay inside all day and night. I would look down my street and not see a single person, not a single sign of life.
