Fire and Ice and Everything Nice? Or Not?

I'm a huge fan of Frost to be honest, my favorite poem will probably always be The Road Not Taken and in second place would be Stopping by Woods on a Snowy Evening, but instead of writing about something I like I wanted to talking about something that intrigued me, which was Frosts Fire and Ice.
How often do we freeze people out when we don't like someone? Growing up the best way I got back at people was to give them the cold shoulder and boy was I good at it too. Sometimes giving the cold shoulder lasts a lifetime then when something happens to one of the people, the other person feels terrible because all they had to do was say they were sorry.
How often do we get so angry at people that we say things that we don't mean. Our anger and hate hurts the people around us, most of the time someone that has nothing to do with the situation that you are angry about.
I guess I just like that Frost kind of tells it like it is.
