I am newly independent, but I’m not celebrating. On Monday, my husband Bob and I joined the ranks of empty-nesters when we dropped our son Luke off at the U.S. Military Academy at West Point. His departure was early (6:00 a.m.) and abrupt (30 seconds to say ‘goodbye’), and the separation feels permanent. Luke is no longer ours, I’ve been told by those in the know. “He belongs to the army.” Ouch.
