It is essential not to let them overcome you and stay calm even if a situation is insulting. Do not forget that being too emotional make you look like an impolite or impatient person. It is better to prevent such a behavior and you will seem to be a self-confident and smart person. None of the famous politicians, scientists or web developers act too loudly or show their wonderment: they will never demonstrate their emotions in an intemperate way.
