When my friend H was absent from university because he had gone to a symposium, a professor of him asked us to help with moving an experimental instrument. After we entered the professor's laboratory, the professor revealed his real intention to us. The professor said "That fellow(my friend H) is always absent whenever I need his help."
A few days later, my senior researcher suddenly told him(my friend H) the professor's statement. Because my friend H became nervous about the professor's mood since my researcher's exposure, he retired from his part-time job which is likely to disturb his experiment schedule.
I guess his reaction was too sensitive.
But, what was the wrongest is my researcher's careless exposure.
By the way, he won't realize that the cause of my friend H's retirement is assigned to his exposure until visiting this page.
