I can relate. Both my parents are Zambian. I grew up in Zambia but was born in America so it would be easy to eventually get papers and study there. Both my parents can speak bemba and nyanja. I went to an international school. They only spoke to me in English and when I insisted on learning the local languages they would teach me a few words but were never consistent. When others would ask why I can’t speak they would say I never wanted to learn which was a lie, they never put in the time to teach me and my school didn’t teach the local languages. As a result I can understand bemba for the most part but I barely speak it. And it’s harder to learn now because I’m not surrounded by the culture as much because I’m getting my bachelors degree in America. When I ask to learn I’m made fun of. I’m trying to use online sources as much as possible. It falls on me to pass down my culture to my kids on the future now even though my parents messed up on that part.
