Is my brother's behavior normal?
Okay, so Im 18 and my brother is 11. He has always had an abundance of issues. He still pees in the bed, he's bullied at school, he has a learning disability, and he's slow with everyday tasks. I can handle all of that. Its what big sisters do! I taught him how to read and how to tie his shoes. Shit, I potty trained him because my mother wasn't active. The thing is, he has also always had a problem with stealing my things. When I was younger, I would be upset and punished him by making him work to reimburse whatever he took or keeping him in his room but I also realized that some kids do that. I myself got caught with my hand in the cookie jar sometimes. Plus, it was nothing I valued that much. However, he has definitely gotten a point where he's a bit too old to be taking everyone's things. My dad doesn't buy appealing food anymore and has even put a camera in the kitchen because of how much he steals.
Now, Im back from university for winter break. My boyfriend is in the military and sends care packages whenever he can. Because I'll be at my family's house for the month, he's sent a few here. They make me extremely happy and I find them important because they're my only connection to him. I know my brother steals so I put it on the top of the cabinet directly in front of the camera my papa installed. Guess what I found this morning? The box open with my shit hidden in my brothers room. Im angry as hell. I don't want to hate the kid because he is a kid and my little brother, but Im getting to a point where I have serious disdain for him. I had patience for him a while ago but that's run out. My dad is too stubborn to take him to a proffessional.
Oh, it gets worse! Apparently its worse than I thought. He steals from school, he steals from stores (even when he has the money to just buy it), and relatives dont want any of us over anymore because of what he does. You remember that bullying? He's bullied because he steals shit. We're not poor. My mom is gone but my dad has a good job and a decent house in the suburbs. If he would just ask, chances are he would get it. Is my brother's behavior normal? If not, what can we do?
