have you ever thought about the possiblity that things you feel, see, hear, smell, and taste are different from the way they do to other people?? like, what if you tasted an apple, and you handed that apple to your friend. they take a bite, and explain to you what it tasted like to them. but when they explain it to you, the explination you hear is just how it tasted to you. but, they're actually explaining something else, and it actually has a different taste to everyone who tastes it... or like, when you're with someone and you hear a sound, and the other person hears the sound, you both actually hear two different sounds. and when you ask the other person what it sounded like, the explination they give just computes in your head as the answer you expected to hear. although that's not what they were actually saying... i dunno if that makes any sense, but i've thought about that a couple times, before.
