My wife works as a nurse at a general hospital ... - Since my husband, I, is a medical device maker who sells outside, sometimes I had the opportunity to visit the hospital where her wife works for her work ... - The other day, I went to an appointment with my wife's hospital director, and I happened to find a video-like file on my laptop in the director's office. - I wondered what it was, and I was curious and casually tried to play it.
