Correct every tiny mistake people make while they’re talking and you’ll be right, and eating lunch alone.

Being right about a word is worth very little compared to what the correcting habit costs you. Each small fix tells the room that you are keeping score, and people go quiet around anyone who does that. They are not wrong to. Nobody wants to tell a story with an editor sitting across the table.

Let the small ones go this week unless the mistake actually changes the meaning. If it matters, say it after, to them, not in front of everyone.
