Regret what you say to the one you love

One time i was at my house and me and my brother got into this huge brawl. I don't remember what it was about but all i remember is that we were hitting each other and a bunch of things got broken. I was so mad that i actually told him that i hated him... At that time i did not regret it at all cause i was so mad but after a couple of days and not talking to him i started to regret it. I felt really bad and upset with my self, i couldn't believe that i said that because it is such a strong word. Now these days when we get in fights i never tell him that, no matter how mad i am at him. After that i spent a couple days apologizing to him because i love my brother with all my heart and sometimes i don't think he realises that. He is my best friend and i would hate to see that change with one single fight.
