USA: People are so, so, so kind. Like, incredibly so. I come from a part in Colombia where people are famous for how warm we are, but in contrast Bogota is a cold shithole with people that would walk over you if that gives them one more minute in their lives. I was expectinvg the worst for NYC, thinking it was going to be worse than that. Nothing furthest from the truth. People were always kind, polite, ready to help you even if you didn't ask for it. It was a really heartwarming experience. Double fuck Bogota after this, you pretentious assholes.
Food portions are just too damn big. I wanted to get a "traditional american breakfast" and was presented with 5 very thick pancakes with syrup, bacon, all that stuff. I felt like my cholesterol was shooting to the stars, and don't get me started on the size of the other meals!
One kinda bad thing was that food is really savourless there. Like, I understand why sauces are important, everything tastes like water by itself. I assume it is because out-of-farm food is really expensive, so the "normal" food is all preservative filled. it's just not the same.
