Silas ~ Well, I suppose Slag can't 'prove' the truth of the story; but why should he be expected to? If we were all called on to prove the truth of any and every assertion we made, an intolerable situation would result. In even doubting Slag's story's truth, you are, in effect, calling Slag a liar, with [as you yourself have admitted] no proof to support such an accusation ~ to which, even if you defend it as 'merely an opinion', Slag is surely perfectly entitled to object. I think this goes well beyond 'merely stating an opinion', into the realms of wanton and needless insult. It was obviously a disagreeable experience which Slag was recalling, and to have its verity thus brought into doubt must have been exceptionally distressing. No wonder he thought the person who could do such a thing, with no sort of evidence to back up such a doubt except reliance on a 'bullshit detector', had 'something wrong with him'!
