Empty Car Syndrome??

I watched both of my children head off to college many years ago and never really suffered too much from 'empty nest syndrome.'  Now, however, another passage in my life is coming to an end and I'm not sure how I feel about it.  Since 2007, when my daughter was deployed and 2008 when my son and his family moved back to Fort Wayne, I have been driving one or more grandchildren to and/or from nursery schook, kindergarten and on into grade school at least two or three times every week during the school year. For a few years it was every day.  I rejoiced when the youngest was finally old enough and tall enough that I didn't need any child car seats in my car.  They could buckle their own sear belts and life was easy.  Now my youngest grandchild will be graduating from 8th grade in five weeks and suddenly I won't need to pick up anyone after school (at least not on a regular basis). Part of me is rejoicing, knowing I will have a more flexible schedule but part of me is realizing that I am really going to miss those after school conversations. Thank goodness they do all still text me.
