Whenever we come across people who just don’t get it and/or aren’t the smartest, we sometimes get fed up and frustrated. Learn to laugh at people’s incompetence instead of getting mad. Not everyone was born with common sense and will never get things exactly right, therefore it’s a waste of your time to get upset with them.
Getting mad at someone’s inability to appear intelligent will not make them any smarter. Let things go and forget the stupid people in life. It’s better to laugh at the foolish rather than try to change them, just because you are bright does not mean everyone one else is.
