I think this tends to happen when people move away from their homeland and raise their kids elsewhere. Especially if your parents are committed to Americanizing. I’m not sure how else to understand them not teaching me so much basic stuff about the biggest holidays of my culture. Like New Years related things, for example. It makes me sad that I celebrated half of only some holidays.
Honestly maybe it’s because they were poor. I will ask them about this. Poverty probably changed what traditions they practiced.
Traditions and cultures are only important if you make them important to you. If you want to learn how to cook certain dishes or how to celebrate, there’s tons of content on video platforms. Maybe try making some friends from your culture, online if there aren’t many in your area and celebrating together. As for your parents, people have all sorts of reasons for abandoning cultural practices, maybe it’s poverty, maybe they have trauma attached to them, maybe they wanted to protect you from the social consequences of being different - you never really know unless you talk to them. Sometimes people move to get away from cultures, you know? Not saying that’s necessarily applicable for your family but don’t blame them too much 💜
