Rules and culture I always loved to know how does a person form another side of globe live. Walking on the bookstore, the biography and travel books are the most attracted me. Understanding the history of a country we can understand your people. I believed that it was enough to travel to anywhere. My first travel to US, on 2006, was terrific. It was a business travel to my company branch in NYC. It was a week before the end of November and I was exciting to see the Thanksgiving Parade. After work, I ran to stores to buy all the stuffs that my son asked me. On of these days, I went to a market to buy some candies. Next me, a lady had overthrown their purchases on the floor and I immediately tried to help her. to my surprise, an act so gentle became something very offensive, because the lady said she had not asked for my help. I was so upset and commented it to my branch workmate and he told me that it not common to happen but when something like that happen it will be better to ask or offer a help first. Yes, my friend! The books doesn't give you that experience. Each culture have your own rules.
