When you've been doing something one way for so long, and then realize you've been wrong this whole time, you are usually in denile.
IE: I've been writing "as opposed to" like this: "as a posed to"
HONESTLY all of high school I did that. NO one corrected me. I genuinely thought, up until tonight, thought it was the correct way to write this.
I'm heartbroken. Maybe that's not the right word. Stunned? Shocked?
Either way, it's a weird feeling.
It's like being told your mother is alive when all your life you thought she was dead.
