To be fair, you never do know. I had a friend who insisted she hated all fruit pies, especially apple. Not being one to do the "You just haven't had the right...." (and perfectly happy not to share apple pie) I just let that one slide by. Until she mentioned once that she didn't see the appeal in "applesauce in soggy pastry." Well, after I picked my jaw up off the floor, and recovered from the shock, I inquired further - surely she had experienced real apple pie at one point (no apple pie I have ever encountered could be described as applesauce in its entirety). However, further probing proved that, no, she had never had apple pie with chunks of actual apple. It was applesauce consistency and wet pastry. At that point I did go so far as to suggest that, perhaps, she had simply never had good apple pie.
Unfortunately, she explained that the apple pie in question was her mother's.
Fortunately, she agreed with me that it was likely a poor pie, especially after I described what I know to be apple pie.
We subsequently made a fruit pie together, and she sampled my apple pie at one point, and allowed then that while these would never be her favorite dessert, there was some previously unrecognized merit to the whole food class.
So, as I say, you never do know.
