Today morning when I entered my office, I saw one of my colleagues looking unwell. I asked her what happened, and she told me she is suffering from jaundice. Then I told her to take care of herself, and after a few minutes, I saw her coming with the glass of water. Then I said to her that she only needed to call me if she needed anything. Her eyes and her smile told me how thankful she was.
When you do something nice for a coworker, he or she will truly appreciate it and may even pay it forward.
