Whispers.
It flew all around him as Ryan breezed into the office that day. Ryan's smile seemed out of place, as he was typically an amiable man who didn't go about his professional day with a silly grin on his face. It was a bit awkward to look at, making everyone wonder what was happening.
There were many things that went on around Ryan that day, but he went through his day robotically, and he breezed over at work. He did everything as he should, not necessarily doing anything wrong. His efficiency had been mastered over the years, and that did not plummet.
It was like the small 'thank you's' or the smile of gratitude he would give to people when they gave him something he had asked for or completed a task. His mood was so good that the whole company learned about it by mid-morning. Of course, that was easy because there was an internal forum that they took advantage of.
