I have come to trust my instincts, too, MARYPAGE. I do, though, try to keep an open and
impartial mind and not pass any final judgments on anyone until I have some evidence one way
or another. As you say, some immediate dislikes are rooted in incidents/persons that we have
pretty much forgotten otherwise.
Having said that, I can say that on three occasions in my long life, I have observed a newly
engaged couple, and felt that there was something wrong there. Nothing overt, just a gut
response to body language, I believe. In all three instances, the marriages did not last very
long.
