If a tree falls in the forest and you are not there to hear it, did it make a sound? Our ears are very sensitive to vibrations in the air. Those vibrations are sound. Our minds take those sounds and turn them into comprehensible noises or words. If a tree falls, it vibrates the air around it. If there are no ears to pick it up, it didn’t make a sound, or did it? The answer is entirely up to you. How aware are you of your surroundings?
