reason behind title

Not even close to empty. I'm only 43. Four kids. Only one that lives at home. So too young to be an empty nester....thus the title. Two kids on missions. One living only a half an hour a way, going to college and soon to be married. My youngest has some "issues" that may mean he needs to live with us for a long time.....thus another reason for the title.
I am not that old but have had a lifetime of many challenges, struggles and good fortunes. I feel I am just beginning a new life, a new outlook and a new sense of well being.....thus another reason for the title
