The Giggle Worthy Parts of Culture Shock

So, I've been in the US for a couple days now, and I've definitely had some moments of culture re-adjustment. Here are lists of how the cultures have surprised me over the last few days.

Surprises in America

• Self-flushing toilets. They surprise me everytime. I didn't even realize that Brazil didn't have them until the first time I used the bathroom in the Dallas airport on my way back to Hawaii. So surprised. And they haven't stopped surprising me yet. 
• Hot water coming out of the sink faucet. What's a water heater again? You mean I can choose the temperature of the water I want to wash my hands with? That's weird. 
• Beverages are HUGE here. I guess I got used to the small size of drinks in Brazil and I'm amazed at the size of cups for all things: coffee, soda, tea, water...it doesn't matter what it is, the cup will be huge!

When Brazilian Culture Has Taken Over

• I want to give everyone I see a kiss on both cheeks. It's ridiculous. Even my parents. I was so looking forward to all the hugs and real, warm embraces that I didn't realize how much it'd become second nature to kiss people's cheeks. 
• I miss speaking Portuguese so much! It's only been a few days and already I'm missing the language so much! 
• I don't automatically dislike talking to strangers anymore. I've gotten used to talking to people I don't know at all, and now I actually do it without thinking about it. It's starting to come naturally, which is crazy, especially if you remember my previous dislike for strangers. I mean, I talked to a random guy at Radioshack the other day and it was totally comfortable. Before Brazil I would have been super awkward and all flustered to talk to a random person. Not anymore.

So, those are just a few things that have stood out to me the last five days. I hope you can understand the shock that happens in my head each time. There really isn't any way to describe these things except for culture shock.
