Q.친구가 실수할때 나둬야 할까요?
There is an ongoing debate over pros and cons of whether you do or say something or not when your friend makes a mistake. Almost people, perhaps most, are against this stance because they think that their friends will receive their sincere advices in their friendship and their advices will not destroy their strong relation. However, others raise the objection because the closer relationship is, the easier the relationship can get hurt. I agree with the latter position and present reasons below.
First of all, firsthand advices and action for your friend might have possibility to hurt to your friend. The rationale behind this is that your friend deeply might have considered you as being who is able to understand his situation in his shoes no matter what. In order wards, your hasty saying and helping might threaten your firm relationship with your friend. For example, when I was a freshman in my university, my best friend and I were taking the science class. During the class, he asked odd questions to the professor and this obstructed proceeding the lecture and made the professor embarrassed. As a best friend, I told him not to do such things, but he was very angry with my saying because he thought that I didn't understand his curiosities and was not on his side. Likewise your advice or action could be impolite to your friend.
In addition to that, do you think that your advice and behavior for your friend could prevent your friend from making a mistake? I don't think so. Since the person who makes the final decision is not you but your friend, although you have the conspicuous insight for your friend's career, your friend would be reluctant to accept your suggestion. To be specific, my friend was trying to enterprise the event company which supply some beautiful narrate models and surprise party to costumer. My country economic situation was so worse that I suggested him to delay his new business plan. However, his belief about his burgeoning business was so confident that I could not induce him. At the result, his business was bankrupt and he has suffered from the people who landed him some money still now.
To sum up, everyone might hold different position on this issue. All the things considered, I am for the idea that you should not do and say something when your friend makes a mistakes because it'll destroy your friendship and the most important thing is to understand and sympathize your friend after your friend makes a serious mistake.
