Is it better to be serious or casual?

The correct answer is: serious and casual! Why? ! Because the world is a world of spears and shields! Seriously and casually complement each other! It depends on how you grasp and use it! If you are too serious, it means rigid, if you are too casual, it means sloppy or dissolute. People naturally think you are biased or there is something wrong with you! When dealing with serious matters or talking about principled positions, or talking about institutional norms, we should be as serious as possible! When dealing with life, entertainment or informal occasions, such as eating, drinking and having fun with friends or talking and laughing with male and female friends. Then let nature take its course or relax your attitude. At this time, you can't be too serious! Just like when we usually eat, we will feel sad if we eat too much, and we will feel sad if we eat less! People will feel comfortable if they eat properly! Ok, my friend, you are satisfied with this answer, please adopt it! Thank you! !
