Nah, my German granddad didn't speak it, ever, because of the wars. My Norwegian granddad refused to let his kids learn it because he was mocked too much as a kid when he could only speak it. Hence Et veldig ubrukelig språk -> A very useless language
Didn't stop him from using drettsekk (sack of shit) as a nickname for his kids and grandkids, though. Miss you, grandpa!
