Here are David and Grandpa Mike observing/discussing cows.
Grandpa Mike took over story time again that night, and even stayed home Sunday morning with David (who had a bad cough and couldn't go to nursery Sunday School). David and Grandpa Mike were such good pals that I offered my dad a job as our nanny, but he respectfully declined and decided to return to the exciting world of aggregates. So David's last adventure with his grandpa (for this visit, anyway) was taking him to the airport (in the middle of the storm!).
