Arguing.

I think that arguing with someone does not help,there are many bad aspects of arguing with someone.
First, we get angry, our faces get red, our eyes get horrible and we start yelling. We start to say bad things, and we can hurt the other person, because sometimes being angry convert us in turns us into bad people.
Arguing is an unsless useless thing, I much prefer talking quietly and sharing our thoughts politely, without yelling, because the one who is yelling does not really believe in what he's saying. (Or I would probably say "he who yells doesn't really believe what he says" - this sounds more like what you'd read in a book, but the version above is perfectly correct too!)
