That is usually from people who THINK they are so much smarter than anyone else. usually moderately high IQ people who are a little smarter than others, who think they are brilliant. And can’t wait to show everyone how smart they are.
The REAL smart people I’ve met are more inclined to listen rather than talk. I keep telling my children that “you never learn anything when your mouth is open” let other people talk- you’ll learn what they know (or don’t know)
Just make sure you also tell your children not to confuse your advice, which is found in the Bible, with the suppression of speech they’ll encounter from the left and the deep state.
