It drives me nuts when people say "good" instead of "well?"
Am I a snob because I like to use "well" as an adverb (because it's correct) and I like other people to also?
For example, I far prefer, "it's going well" to "it's going good." I tend to really like and appreciate people who use the word correctly, and I also assume they're more intelligent. Not that I'm super judgemental of people who say "good," I just wish they didn't.
