The expression "throwing a show-off" usually has a negative connotation. So they say about a person who is trying to show that he is richer, smarter or luckier than he really is. In a word, he tries to make the most beneficial impression on others.
Low self-esteem
One of the reasons for "show-off" is low self-esteem. A person seeks to assert himself among others, to show that he is superior to them in some way. When such a desire is observed in a teenager, there is nothing wrong with that. It is generally common for a person in adolescence to look for his place in life, the desire for others to see him as a person. You can stand out from the crowd in a variety of ways, from winning a competition to jumping from the third floor. Both require some personal qualities. For example, in the first case it is knowledge and skills, and in the second it is courage. In order to "throw a show-off", no qualities are needed. You can, for example, pass off cheap clothes for expensive ones, tell everyone that you are going to the Canary Islands this summer, or do something else like that. That is, to ensure that they begin to envy you.
A person with normal self-esteem usually does not need to pretend that they are better than they are.
Ponty - useful or harmful?
There are cases when it was the show-off that forced a person to start working on himself. At first, he passed off wishful thinking, then it was too late to retreat, and the person in the end achieved success in the area he needed. Other cases are known as well. A person tried to appear better than he is, made an impression on those around him that he was rich, brave or lucky, was very afraid of being exposed. For some, the desire to keep their secrets causes serious complexes. Others, at the slightest threat of exposure, break off relations and may even reach the point of crime.
Severe complexes do not arise very often. Most people, after leaving adolescence, also lose the desire to "show off".
Can we get rid of this?
You can get rid of the desire to "throw show-off". It is enough to understand that each person is unique, everyone has abilities for something, everyone can achieve success in something. You need to learn to see in everyone its advantages and be able to forgive shortcomings. The ability to evaluate what is really needed and what you would like to get in order to impress others also plays a big role. To do this, it is enough to understand what others think about the same - how to impress you. They also "throw show-off", some with more zeal, some with less. If these are people close to you, you can just try to talk to them frankly, explaining that you wanted them to please and see that they want to please you, and that you do not care if your interlocutor has a prestigious car, high-paying job or branded clothing. This kind of frankness will greatly simplify the relationship and help increase self-esteem for both interlocutors.
