I worry about the educational differences, as well.
I have a BS and MA, and plan to begin doctoral work in Fall 2013. My husband only has his high school diploma. It doesn't matter much to me, because he is a warm, charming, charismatic, intelligent man, but I can tell it bothers him. He gets irritated when I use "big words": For instance, I said something about anthropomorphizing our dog and husband was like: "WHY DO YOU HAVE TO USE BIG WORDS? Why can't you just say 'Don't talk to the dog like that'?" He has also grown to hate the word "cognizance."
Maybe that's just us.
I don't always know when I am using big words (it bugs my mother), but if he is actually shouting, rather than joking, it sounds like it is time to have a talk. As you become more comfortable with the big words, you should be able to judge register better. However, there is a point in learning new vocabulary where we like to try out our new words
. If you can explain to him that this is what is happening, he may realize that you are using these words precisely because you are not entirely comfortable with them, either. It is part of a learning technique. Otherwise, he may be seeing it as you showing off or leaving him behind.
He said it in a half-joking, half-serious "eye-rolling" kind of way, I think, but thank you for acknowledging that because, yes, shouting would definitely be a problem!
As far as learning new vocabulary, you are absolutely right--that is what I am doing a lot of times. I have started a running list of words that I've never heard or heard/read that I never really new what they meant and I like trying them out in sentences.
I appreciate your comment!
