I've been going through the exact same thing lately as #4 child is just finishing up college and comes and goes. For the first time in 28 years it is often only my DH and I at the supper table. It is just another chapter in my life. My kids aren't that far away and I have lots to do to keep me busy. DD#1 thought I'd be lonely so she got me a dog! Molly is a great little Cavalier King Charles Spaniel and perfect walking buddy.
