Mine are 37 and 30...and I really didn't experience the ENS because I got divorced at the same time the kids were leaving...then met and married William...life was a flurry of activity. I got a new job, all of that.
When I did finally start feeling the pains of ENS, I volunteered at Big Brothers/Big Sisters... I had a wonderful teen girl to hang out with and do things with... it was fun, and I made a wonderful friend! :)
