How do things fit together perfectly?

How do things fit together perfectly? It’s like when you find the exact right puzzle piece for a spot on your favorite puzzle.

Puzzle pieces are shaped just right so that only one other piece can go in its place, and that makes the whole picture look nice. That's how things fit together perfectly, because they're made to match each other, like best friends who know exactly where to stand.

If you have a box with a lid, the lid only fits on the box if it’s the right shape and size. If you try to put a round lid on a square box, poof, it doesn’t work! But if the lid is also square, it clicks into place like a happy song.

Sometimes, things are made with special care so that they match up perfectly, just like your favorite pair of shoes. You know exactly which shoe goes on which foot because they're made to be perfect matches, and that’s how everything can fit together in the world around you!
