Married 40 years and still have one in school. I don't think I will ever experience the empty nest. My oldest is 24 yrs older than the youngest, now 15. I have 3 grand children. House is always full. We will soon be building a new home on 40 acres. My son now lives there in a mobil home. We will plan the home to accomadate all the kids and grandkids. I have always told the kids and close family that they are welcome to stay if in need. I have made it clear, I will provide the roof over their heads and food from the cupboard. If they need money, they will need to earn it. My oldest daughter moved home after 10 years of marriage and started over. She now has her own home and is engaged. - I do have moments when it seems empty. I have joined a quilt guild and have been able to do things for and about me finally. So think of things you have been putting off. But always be prepared for a surprise return.
