Reevaluate your methods for dealing with arguments today, especially if you think that giving someone the silent treatment is a wise and mature idea. Ignoring or avoiding someone you're having a dust up with isn't going to do you much good. After all, how are you going to clear the air when you won't even talk to them? So grow up and step up: and have the conversation you need to have. Decide to be compassionate and honest. It's going to lead to resolution.
