The other day I was trying to think of a describing word for "someone who doesn't share the same enthusiasm"
"After getting an A in my exam, I danced around my ______ classmate. He got a D."
I'm looking for the describing word for that classmate who did not share the same enthusiasm.
Edit: The above is admittedly a poor example. Here is another attempt:
My wife and I took a "which dog are you" quiz. After getting 'pit bull', I began shadow boxing around my ___ wife. She had just gotten 'poodle'.
