#9 Silent for good

Well there has been statement "Silent is gold."
But here, I mean it because this is important. Well as we know that there are many people who talks bullshit or just do the talk without any work. Well that example is also one of lots beneath this topic.
What I learnt today is silent in everyday conversations. I need to know there is time that is better for me to shut my mouth, or it is just the time.
I was talking about stuffs and people, and everything went just as usual, until my friend said that she didn't like what I said then. It was just about simple things, and I didn't mean anything nor expect her to give me that kind of feedback, cause i don't really mean a thing.
By the show on her face I can simply have this conclusion: She really hate it and she meant it that I shouldn't repeat what I did.
At that moment I thought of this: There are so many people who treat me or do the thing like I did, but for me it's fine because I understand the circumtances. But as we know that no human being has the exact personality, and that is why I need to filter the words before I speak.
I am really thankful that I have a friend who can push me to write my previous post, because that helps me to deal with this.
