Possibly was a census worker, possibly was a scammer. But, as Mudwhistle pointed out, most scammers use charm rather than alienation. Sometimes they try intimidation, too.
But flat out calling Pixie a liar without any foundation for it is wrong (not that you did). I have no foundation for calling you a liar, nor do I have for Pixie.
Anecdotes are evidence of nothing and I have no doubt that Pixie knows that, but I will not be hateful, especially when she is having other health issues with family.
(I know that is JenyE's style, though.)
