Umbilical? as in receiving nourishment? not from the wts.
I kinda look on it as the VFW, veterans of foreign wars. They still meet and keep in touch but they sure wouldn't want to be back in the war. They show family and friends war scars and medals, and share war stories over and over again.
It's an experience we all went through, like high school maybe, only worse, [if that's possible] but we keep in touch and go to reunions. It's a part of our lives but it's not our life.
