Imagine your nose is like a really eager puppy. When it first smells something new, it gets super excited and barks loudly to tell your brain, “Hey! There’s a new smell here!”But if the smell sticks around, your nose puppy gets bored, just like how a real puppy might stop barking at a squirrel if it stays in the same spot for too long
