Why Do Waves Always Meet at the Same Point?

Imagine two friends running toward each other from opposite ends of a hallway. No matter how fast they run, they always meet right in the middle, that’s like waves meeting at the same point! Waves have energy, and when they travel toward each other, it makes sense they would meet halfway, just like those friends. It's all about balance: one wave comes from here, another from there, so they naturally meet in the center.
