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"
I live in a high altitude area. It gets very hot. People will say that it's because we're "closer to the sun" as if the 6000ft/1800m difference is what matters vs the 93,000,000mi/150,000,000km distance to the sun is affected by something so small.
The difference is the lack of atmosphere to soften the various types of light from the sun.
You can't expect scientific nuance from most people. They think in Lies to Children and remember the middle school eclipse demonstration with the lightbulb and rubber ball and that's about it.
So not to be pendantic (lol), but this is the definition of a pendant:
noun
noun: pedant; plural noun: pedants
a person who is excessively concerned with minor details and rules or with displaying academic learning.
With pedantic of course meaning acting in that way. I feel like pointing out my technical knowledge is unnecessary in the grand scheme of things but even if I try to let it go my brain will hang on to it until I tell them, even if that is much later on.
