Sure. There was a class reunion where a student who had been bullied in high school was welcomed with open arms. The bullies had grown up and apologized sincerely. It was a very touching moment. Another one was when a disabled student from high school was able to attend the reunion with the help of his classmates. They all made sure he had a great time and included him in everything.
I know of a high school class reunion story where a former classmate who had served in the military and had some tough times came back to the reunion. His classmates honored him with a small ceremony. They listened to his stories of heroism and sacrifice. It was a really heartwarming display of support and respect for their classmate who had served his country.
