Any recommendations on Japanese songs?

Life note 1 Today I had a conversation with my retired father and it was like this: " You should find something to do. Having life focus can make one live longer and happier. It doesn't have to be a paid job." I said to my dad. " I know. I just need time to search what kind of thing I want to do." My dad replied. After the conversation, I pondered a bit. I think I am right about suggesting my father getting something to do for the rest of his life. Meanwhile, I also feel the importance of developing second or multiple interests besides job skills. One thing is that those interests can invigorate our lives; another thing is that they may possibly become our career tools. And they can also be our life center once we retire. The reason why my father needs time to find one is that he did not develop any interest when he was little or young, and he had no time to do it (or he may even not beware of it) after he built the family. Because of my father, I told myself that I should explore more and experience more so to find the one that I enjoy the most. And make it my hobby and interest...

What's your attitude toward the political climate in your countries?

I wasn't that kind of person who cares much about the political issues in my country, but in these two years I started to..., probably  because I have graduated from college and began to live in the real world.  When I realized the politicians in my country care only about their own interests, and did and said things that are against the greatest benefit of the society, I felt angry and helpless. Although it's always the issue in human history, I feel like it's the worst in current society.  Look at the incumbent politicians, who really puts the country before anything? 

What's your opinion in this respect?

The advantage of knowing a language that people around you don't know?

Two days ago, I chatted with an American friend who I used to work with. He said that he knows Spanish, so back to the time we worked together, he always used Spanish to talk to another coworker who also knows Spanish to complain someone. Most people there were Americans, so they would not  know what they were talking about. It got me to think that talking in a foreign language in such an environment  is indeed advantageous, but what if someone knows the same language as well, and knows you are talking bad about people you both know?

I myself also had the same experience. At that time, I thought it is a good way to vent by speaking in a language people around me don't know. But I think it is somewhat impolite now. Especially when you are the one who doesn't know the language. You would suspect whether they are talking bad about you. By and by, the atmosphere would be teeming with distrust...

Do you have any similar experiences ? or what do you think about this?
