1. grammar police
2. the dark ages
3. more expressive

I dislike grammar police, and I've noticed that many English as a Foreign Language (EFL) learners tend to become grammar police themselves. I predict that one of the reasons for this is that they have been excessively corrected during their learning, aiming for good grades on tests. I personally experienced a similar phase, which I like to call the "dark ages." However, I made significant progress after I let go of that mindset. So, I can confidently say that it's not an effective approach if fluency in language usage is your goal.

Playing the role of a grammar police officer hinders your ability to be more expressive and erodes your confidence in communication.
