My mother spoke it with her parents! My Brothers & I were politely excluded – just learn English was the understood message. After the death of her parents, my mother had rare opportunities to speak Hungarian, and she eventually lost that ability even though it was essentially her 1st language. While growing up one brother learned some from the Hungarian butcher next door (shop on 1st floor & residence on the 2nd floor; a lot of that was the more ‘colorful’ expressions.)
