I have read this in my book:
The author would like to thank the following:
Dr. Jeff Will at Valparaiso University for his encouragement at “just the right time” and his
invaluable feedback during the writing process.
What does the phrase "just the right time" mean? Is it mean "free time" or "the times when the author need the help"?
The exact time that the author needed the help.
