I am a Keeper of my Brother

I feel like I am the keeper of my little brother. I feel this way because whenever he is about to do something stupid, or is debating about doing something stupid, I try to convince him not to. I also try to help him out whenever he needs it and I teach him how to do different things, like skim boarding. Another thing that makes me think that I am his keeper is that I am older than him so I just feel like that I have to teach and protect him from different things. That is why I think that I am the keeper of my little brother Ryan.
