Samantha noticed that her coworker Mark had been feeling stressed for several days. He had been working overtime and looked tired. On Friday, Samantha bought him a small coffee mug with the words, “You’ve got this!” written on it. She left it on his desk with a note saying, “Thanks for your hard work.” When Mark arrived, he smiled for the first time that week. “This means a lot,” he said. Sometimes, small acts of kindness can make a big difference.
