While doing some stuff on my computer, a Skype call came through, so I answered it.

The question: "Is it nine (nice?) there?" was countered with "Nine what?" Regardless of whether the question that was asked, be it "nice" or "nine". Both are relative. If it's nice, it's something relative to me that might not translate across. And whether the caller was asking "Nine o'clock", or "Nine degrees Fahrenheit/Celsius". If I do not know the unit being used, ie, "o'clock" or "degree Celsius" or "degree Fahrenheit", I can't answer.

The next question that came:
"Is it warmer there?" was replied with "Warmer than what?". First, in order to answer that, I need to know what it is being compared to. If I do not know the reference, I cannot give an answer.

The caller then said, "don't worry".

Yeah, I certainly don't.
