Culture shock by Byung noh

I lived in America this summer. I arrive in ball state university 6 week ago.
First, I visited a walmart because I bought necessities of life. And I paid this object.
But, the price add the tax. I was surprised this situation. Because, my country was include tax.
I felt so expensive. I was strange this culture. But these days I understand this situation. Because, I experience many America culture.
For example, Lately I eat America food in atrium and I learn that I see America life style. And so on….
I understand another culture when I experience another culture.
