Did I count right (14)....wow, with that many I don't know how you could be an empty nester until later.
Congrats to you for being able to "make it" with all your children in today's times and to have the ability to do home schooling.
You have a special quality that will be passed throughout your children and enjoyed forever.
I'm 51 and my DH is 56...we are empty nesters and have been for several years now. We do enjoy it and are overwhelmed when everyone comes home to visit at once.
