As a man, your cousin's face is very important to him, and he loves it. This is also a symbol of backbone and a very good start, so it deserves praise and affirmation.
But if you do a lot of wrong things for face, it's not worth it, especially because face makes others make fun of you.
You can gently tell your cousin that if you want to save face and give yourself enough face, it depends on the occasion. If you feel that you are very powerful on any occasion, it is very inappropriate for you to praise yourself indefinitely.
Therefore, we should pay more attention to the occasion, don't let many people make fun of ourselves, and be measured, so as to show that we are mature and respectable.
In addition, your cousin may have a good face and a tough personality, which is good or bad for a person, but we should pay more attention to the bad aspects, pay more attention to what others think of us, and ask for advice with an open mind.
Face-saving people are generally unwilling to lose to others. In that case, you can also convince your cousin that the most important way to win the praise of others is to make yourself stronger. Only with your strong heart can more people look up to you and learn from you, and you will naturally have a lot of face.
In this way, your cousin will really have face, instead of boasting and exaggerating himself, so that others will not be suspicious and point fingers at your cousin.
In addition, as the closest and most trustworthy person around my cousin, you should always remind my cousin to take good care of interpersonal relationships, learn more from the people around you and treat others sincerely. So even if your cousin loves face, there won't be any big mistakes.
