Every time i bring up someone confusing "it's" with "its" or "their" with 'they're" i get downvoted to oblivion and now suddenly everyone cares. Is "how it works" a greater offence than confusing words with different meanings?
Close enough to get mixed up, even if you know they're different words with different meanings. I often swap 2 completely unrelated words when typing if they sound kind of similar in my head. Called "spoonerism" apparently.
