What do my son Daniel and Rick G. have in common?

My family and I lived in North Carolina for six years (1997-2003).  They were formative years for my son Daniel.  When Daniel was applying to colleges a few years ago, he wasn't interested in applying to Duke.  (Daniel is now a sophomore at Northwestern; so Daniel and Rick do not have an undergrad college in common:  Rick attended Duke.)  But Daniel is, like Rick, a huge fan of Duke basketball.  (My other, and younger, son Gabriel--who like my PhD-in-math brother Jim lives in the stratosphere of math and science--could care less about college basketball.)  I just received a text message from Daniel, exulting over Duke's eventual win tonight.  I have many failings as a parent.  One of them:  I raised a son who is in the thrall of Duke basketball.

Go Butler!

(I know, I know:  fat chance!)
