This time, my son and I travelled to the UK together again for the first time in 15 years. It was an unexpected gift to see how much my son had grown. On the other hand, I also realized how old and frail I had become, having turned 74 during the trip. Life is like climbing a gentle slope and then slowly descending. When I suddenly realized this and stopped to look back at the path I had come, I saw that it was not a slope that I could go back up, but a steep staircase with large steps. I am grateful that I was able to realize this. Fortunately, it didn't rain during the 23-day trip..
