His attitude about teaching me the language was strange. He refused to teach even my mother. He was all "Your 'Murican, so you speak 'Murican." And not Norwegian.
It wasn't until I was in my early 20's that I discovered that the Norge my grandfather spoke was essentially a dead language from the early 1800s. Soon after my family showed up here, the Norwegian language changed. It changed a couple of times. Not that he knew that.
But on the German side, my Great Grandmother was all about teaching me German as a little kid. She always kept a bowl of the cheap cheap pressed pastel sugar mints that little old ladies are fond of. It was a decorative milk glass hen and nest covered bowl. I could have a candy anytime I wanted as long as I asked in German. And it had better be in Low German! Or I got a light whack with a little bamboo cane every time I mispronounced a word. I learned quickly!
