Not that confusing me is all that hard - depending on the day and the amount of caffeine in my system - but here are some things I find confusing:
A news headline that states they found water on a comet, but it's not like water here on Earth. So, what? It's not H2O? Would that be NOT water then? So I clicked on the article link to get some clarity, and read where they're pretty sure now that it was an asteroid and not a comet that brought water to Earth. What? Because hydrogen and oxygen and the necessary factors to combine them into water weren't already here? I'm confused.
How people who want to get paid for their work scream when someone else even suggests that they might want to be paid for their work, too.
People who would never give out their personal information to some dude that walks up to them on the street but happily give it to someone who calls them out of the blue.
Rude people. Is it really that hard to hold the door when you see me walking up behind you?
Dietary information on the menus at fast food restaurants. The big M should automatically tell you that it's full of fat and calories, and if it doesn't, the information on the menu ain't gonna help. Sometimes a gal just wants a quarter-pounder with cheese, fries and a large chocolate shake. I know it's not 'good for me', so why rub it in?
The fact that MS Word would like me to change quarter-pounder to something like quarter-ponder or quarter-sounder or quarter-plunder. Now at McD's... The Quarter-Plunder!
People who complain about a certain business to the point of insanity, but then continue to use that business. (It's okay to kvetch every once in a while, but there's a limit there somewhere.)
Humorless people. (Note: I call my daughter 'the humorless troll' on occasion, but she laughs at that, so she's not actually humorless.) Life's a funny place, people. Laugh at it. It'll all go so much smoother. Trust me.
