(I wrote this a number of  years ago, but I can’t quite place it in time.)

Our son seemed to have been born with a predisposition to love grandparents. I don’t know how he came by it; could there have been a genetic cause, hardwired somehow into his wee neural net, passed down from his biological forebears?  Did it come from the books we’d read him as an infant and toddler?  My mind flips through the long lists of titles and book covers, but I can’t find any particular ones that might account for this.  It’s a mystery to me.
