She loves looking through what I pickup at the shows, knows the difference between a T205 and T206, what to look for to tell the difference between a '68 Topps and '68 Milton Bradley, rudimentary knowledge in 'grading' a card (and some might say just as good as a TPG at times), where and how I store my collection as well as the inventory of what I have, and could probably reel off a list of about 20 HOFers.
Oh... Did I mention though that she is my 2nd wife.
