talk talk talk

So this post will be about people.
I tend to listen to people talk more than I talk.
I enjoy it, I think it's interesting. yesterday in math my teacher was teaching us a math method and turning it into a open discussion. All of a sudden, everyone started talking really loud and making comments. When I was listening to this, their comments were things that everyone knows, basic knowledge, and they didn't contribute to the lesson at all. And that got me thinking about pointless talking. Everyone has been raised to know how to hold a discussion, it's proper edicate. I wonder who first thought up what a polite conversation was. I have had so many pointless conversations in my life, not that it's necessarily a bad thing, just interesting. the typical "hey, how are you, what's up" Is usually the conversation starter, then it might warm up to a small talk on how the weather is, how classes are going and things like that. I've noticed that personal conversations, just between two people are pretty civil, quiet and basic. In contrast to a group conversation, Where all at once everyone has something to say, whether it's just at the top of their head or something they've thought about. Anyways, I'm probably not making much sense.. you know, pointless talking. errr typing. that's about it.
