The interplay between short- and long-range interactions leads to interesting phenomena, both with zeolite constituents as well as with those researching them. In considering over a decade of interactions with Prof. Takaishi and his work, on the occasion of his 77^th birthday, it is the number of overlaps in the paths that our separate research interests have followed that is perhaps most notable. It is a privilege to have the opportunity to recount some of these overlaps in a personal fashion and, in so doing, to express my respect for Prof. Takaishi and my appreciation for the many fruitful ideas he has already contributed; I am certain there will be many more.
