Sure. There was a pair of best friends, Emma and Sophia. They were in different classes in high school but shared a love for art. One day, there was an art competition. Sophia was really nervous. Emma spent hours with her, helping her with ideas and techniques. Sophia ended up winning second place. It was their friendship that pushed Sophia to do her best.
Yes. Consider the story of Mike and David. They were friends since childhood. When Mike's father passed away, David was by his side constantly. He helped Mike with all the arrangements and supported him emotionally for months. Their bond grew even stronger during that difficult time. Real friendship is like that, being there in both good and bad times.
