My wife, who had been complaining about some shoulder pain lately, was introduced to a young man named Yokoyama who lives on the upper floor of our apartment, and we decided to take yoga lessons once a week. - I was laughing as I watched my wife seem to be enjoying herself and thinking that thanks to her, my health was getting better, but one day, while trying on some new leotards that I had bought for lessons, I thought to myself, ``Tomorrow... - It's a lesson...'' I felt a little uneasy as I watched my wife work hard to get rid of her hair with a hand mirror in hand.
