This summer, I travelled to Vietnam to visit my family. My family lives on the rural side of Vietnam. Although I was taught the Vietnamese traditions, I did notice many cultural differences.
I noticed that Canadians are more reserved and polite whereas Vietnamese people are more loud and more "out there". An example of what made me aware of the norms I held was when everyone kept offering me food. Out of habit, I would always reject them because I thought of others wanting it regardless if I wanted it. But I noticed when my cousins were offered something, they would accept it no matter what they were given and I realized that they accepted it because they didn't want to hurt their feelings.
I also noticed that Canadians were more independent and Vietnamese people had a more dominant and stricter aspect on gender roles. An example would be whenever I would help lift boxes or move tables and such, my uncles would laugh at me and tell me to put it down because it was heavy. I didn't think it was big of a deal. Then I realized that they didn't believe in gender equality.
I could go on and on. This proves to me that although we may be similar biologically, culturally, we are quite different. The norms that we hold reflect our different cultures.
