Collegiality means being nice and working well with people who are your friends or colleagues. Think of it like this - when you play with your friends, you share toys, take turns, and listen to each other's ideas. Similarly, when we work with our colleagues, we should be friendly and respectful to them. This means we should be willing to help each other, share our ideas, and work together to achieve our goals. We should also listen to each other's opinions and be open to new ideas. When we practice collegiality, everyone feels happy and motivated to work together to achieve our goals.
