Me and my brother want to start boxing each other for fun?

I am 12 and he is 11 and we want to buy boxing gloves and headgear and start boxing in our bedroom. What are your thoughts and advice?|||good|||Unless the both of you have some professional training, I don't think you should do this thing. You might hurt each other more than you intend.|||Don't fight in your bedroom, there isn't enough room. I've taken hits before from a boxing instructor with head gear on and it was that bad.
