If you're aware enough to acknowledge your faults, all it takes is trying to better yourself and apologizing when they get the better of you. We all have our issues, and I would never hold it against you, nor should anyone. If you wrong someone, apologize; and if you're hotheaded and snap at someone, again, just apologize. Things happen, and if you're not content with how you act try to change it, but either way so long as you respect others and act accordingly, you're fine by me.
Welcome back to the fold.
