people who answer statements with questions.
me: the sky is blue.
them: is that right ?
Or any of a dozen responses that are all questioning what you just said.
Damn that's annoying !
People who answer yes/no questions with a vague ambiguity.
Me: would you like a cup of coffee ?
them: are you having one ?
it's a bloody yes or no question, did I say:
"would you like a cup of coffee, just be aware I won't actually make you one unless I want one myself and I had a cup about 10 minutes ago, so it's unlikely I will actually make you a cup of coffee. Not sure why I even bothered asking. "I've more or less trained my mate to just say yes or no.
Anything else and I don't make him one
