Nancy,
My youngest (of 4) is practically 21 -- they've all flown the coup, and two went out west. One is in school up there in Philly! I myself went back to school a few years ago and am now working in a job that I adore, with interesting people and a lot of challenges, so have a new life with new interests. I don't have time to miss my kids, though I truly do miss them whenever I stop to think about it. Also, I can talk with my kids about office sorts of things -- we're experiencing similar things some of the time. I also can't stand to do nothing.
