Red vs Blue:
A lot of Americans in the red states should generally be less awkward when they see people try to record them.

Your English is not as broken as some people haha. You mainly have a different style, a different accent, and things like that. Most people in the United States like President Trump and a lot of them tend to be comfortable around cameras.

But at the same time, I noticed differences between American and Vietnamese when I lived in Vietnam. So, you are right that some Americans are awkward around new people or certain people. Many of the Vietnamese people I met were very open and they treated me like family and I liked that. America is bigger than many countries. Vietnam is like the size of California.

RE: I lost half of my confidence vlogging when I'm in the US. People get kinda awkward ...
