Listen, for the up'teenth time, HOW ON EARTH DID HE DIRECTLY AND INITIALLY INSULT YOU!? he was not aware of your home situation, so to simply go and loose the head like this just shows how little in control of your emotions are. Now, I hope you can agree to his sig now. At least he made the effort to change it. And I went out the way to ask him to for you as well. So now do me a favour, and accept it was all a big understanding. Your no hero, and your just causing unrest.
Oh, and EVERYONE has problems, keep them to yourself. As jac said, you should have taken this personally with him, instead of trying to attract unwanted attention.
