forcing a binary state on an opinion. Shades are OK too. For example: "$4000 is grotesque, $400 is sketchy, anything above $100 could potentially be justified, and below $100 is safe territory". It doesn't have to be binary, but when someone states a certain figure - "$4000 is obviously grotesque" - then a binary state has already been established. $4000 and above is grotesque, below is, well, possibly grotesque, possibly not. Uncertain, clearly. That seems a sensible starting point for a discussion, to understand what makes $4000 grotesque, and does it also apply to $3000, $2000 - to understand the rationale for such a statement. I can't imagine you saying the same to a friend who said "I went for a very long drive last weekend" > "What's the cutoff for long? 50 miles? 100 miles?" I can imagine asking "So how long is long?" I grew up in mid Cornwall, where a trip to Plymouth (55 miles) was generally considered a long drive. These days, I consider driving to Chamonix (780 miles) a long-ish drive, and to Istanbul a properly long drive. So knowing that my idea of a "long drive" has changed over time, and knowing my notion could easily differ from theirs, yes, I'd easily ask what they considered a long drive.
