I guess that’s because when we talk, we make a lot of assumptions, otherwise every sentence would understandably become tediously protracted. Instead of saying, “It’s a nice day,” we’d have to say, “It’s a nice day, but keep in mind that’s only my opinion, and rigorous scientific research has shown that my opinion can be effected by innumerable factors such as my mood, how much sleep I’ve had, the status of my interpersonal relationships, my activities in the previous 24 hours, and my general health, including my emotional, mental, and physical well-being. Also sometimes words are not to be taken literally; I may just be attempting to strike up a conversation with no thought whatsoever to the literal meaning of my words, or for that matter the words I spoke may be 100% percent metaphorical, like if I’m making an inside joke, or quoting a movie line, or I’m making an oblique nod to a cultural meme, and I’m assuming that you will get the reference or in some other way ascertain the hidden meaning of the phrase. Then again there’s chance that I’m being facetious; you and I both know that today is a terrible day, but after all I am known for my biting wit, and making an obviously false statement about such a dreary day may just be my way of attempting a bit of humor to cheer you up. Finally, assuming that I am actually making a literal statement of fact as it pertains to my opinion regarding the weather, I’m taking into account our geographic location and the time of year. In other words this might be a perfectly average day in Summer or in Barbados, but since it’s now January and we’re in Minnesota, well… it’s a nice day.”
So when someone says, “You never know if you’ll like something until you try it,” it’s safe to assume that there are unspoken caveats to that statement, which include the idea that common sense exceptions or practical limitations apply, such as not eating anything that fell out of your cat after a hearty meal.
Salty food in place of sweet food: give it a shot, you may be pleasantly surprised. Sinking one’s teeth into a crunchy feline intestinal confectionery: proceed with caution.
