What's the most petty/pointless/pedantic hill you're willing to die on?
For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don't want to reach under the roll to take a piece! That's ludicrous!
That or my recent addiction to correcting people when they use "less" when they should use "fewer"
It's a noble fight, but a losing one. Language changes so fast and since common people make common usage, we're bound to shift over time to something truly incomprehensible like actual Old English is to what we speak today.
A fact is an observation made in nature. At 8:40 PM PDT I read from my kitchen thermometer 73°F. One datum.
So often people use the term fact to suggest something is true, e.g. Gravity is a scientific fact. It's an easily demonstqble phenomenon. There's a mathematical law that predicts the interval of falling bodies. You can make and present facts that demonstrate the consistency of gravity, but it isn't a single fact in itself.
A while ago I had people arguing with me that the word "is" means basically the same thing as the word "was" and that I was being pedantic by saying it didn't.
