Speaking from experience
My wife and I are shedding as many possessions as we can, stuffing our Jeep full of what’s left and moving from Chicago to Seattle this week. I’ve probably gotten “bring your raincoat” 20 different times already when I mention the move. I found myself getting annoyed by this and at the same time realizing that I have been guilty of the same behavior. Which is repeating things you’ve heard or read but really don’t know from experience. It’s not that Seattle isn’t rainy but more so that a good 75% of the people who said that admitted they’ve never been there before. If the value you’re adding is repeating something you heard or read then it’s probably best to not speak.
