Getting old--er

One of the many benefits of getting old--er is that you have many kids of several generations to compare!  I have two granddaughters that did not grow up close by, so we had to work hard to keep a relationship going.  When they would visit, we would do several things that had meaning to us and them.  One of their favorite things when they were about 8, maybe 9 was to take orders for dinner.  One of them especially,  Gienah, would be very serious.  She would put on an apron, get a tea towel draped over her arm, and with a pen and tablet would circle the room taking "orders" for dinner.  Even from me and I was the cook!!  What makes it cute? funny? was that 15 years or so later, a new granddaughter Sierra raised in my house!!  enjoyed doing the same thing!! And---4+ year old great granddaughter, also in my house in her turn, does the same thing!!  None of the girls knew each other--Gienah was 13 and lived in Florida when Sierra was born and Sierra was 6 and out of my house when Anaila was born!!  Does this mean that girls instinctively cater to the wants and tastes of the members of their family?  Did I forget to mention that these girls had different mothers and did not grow up together?
