I was out there meeting with a lot of working moms and whenever I would gather a group of women, there was always a voice that was unfamiliar to me, and it was the voice of a military spouse, oftentimes a woman, oftentimes working, many times in a position where they've had to move every two or three years, where their kids have had to change school multiple times, people dealing - families dealing with multiple deployments, dealing with the stresses of reconnection.
