Imagine your body is made of tiny blocks, like Legos. Walls are also made of tiny blocks, but they're all stuck together tightly. If you try to walk through them, the blocks get in the way, just like how you can't push through a pile of bricks with your hands.
Examples
- Your hand can't push through a brick because it's too tight.
- Walking through a wall is like trying to walk into a pile of bricks.
- Imagine your hand being made of blocks that get stuck in other blocks.
