For me it stands out like their/there/they’re, and you’re/your, used interchangeably. I’m not going to judge you as a person, but I will judge you education as clearly and significantly inadequate. And I will definitely feel truly sorry for you, having to go through life with a habit that screams ‘not so smart maybe’, to all and sundry whilst you continue merrily along in blissful ignorance. Especially if you’re otherwise intelligent, and seemingly well spoken.
How does a person get through middle/high school or any post secondary education without correcting these basic errors, in a language that is their first tongue?
But does anyone correct others on this front? Your work colleagues, or spouses, or siblings? I can’t bring myself to, to be honest. I love and respect this person and don’t want to offend them, so I say nothing at all. Just feel increasingly embarrassed for them, and then wonder what I myself do that makes others similarly cringe.
