Not necessarily, and, no, I don't think a person looking for any possible sign of a clue is going to read "too little" into something. But opinions vary.
Well, I wouldn't know about that. But in any case, I'm afraid you missed my point. My apologies for not making myself clear.
As for Ckret, he didn't use the word "prove" but he said we"know" ... and in such context, it wouldn't appear to me that there's much difference in regards to his confidence and certainty on the issue. It would seem simple enough. But I guess it shows that people can disagree on simple things ... like apparently the definition and usefulness of of the word "giddy," for instance. :)
