Before the Coffee Gets Cold

Summary  There is a cafe that has a table where a person can travel in time. There are rules that must be followed. 1. You can only see people who have visited the cafe. 2. You cannot leave your seat while traveling. 3. You have to drink the coffee before it gets cold. There are some realities to know. Nothing a person does while traveling changes what has happened in the past or choices people make to current time. 
My Thoughts Each chapter focuses on an individual who chooses to travel in the cafe. Each has their own reasons and none of them are sure what they expect to get out of traveling, knowing they can change nothing by traveling. 
What each finds is that they themselves change with traveling in some way. They gain understanding they did not have before by having the opportunity to have conversations they did not have and wished they had. They come to see more of the picture the dispels fears or assumptions they had about other's thoughts and motives. 
The title itself is a proverb. Drink the coffee before it gets cold. Enjoy what you have while you have it. If we hesitate, if we let fear cow is into inaction, we miss out on what is good in our lives. The message is simple and the stories are not high action. The characters bring the parable to life. I read the English translation and the word nerd in me wishes I could read the original Japanese with a full understanding of the culture. I think the prose would resonate more deeply, even, and one may find even more parables within.
