Raptor Fifth Wheel

I met him like 3 years ago, in fifth grade. The only thing we had in common at the time was that we were both in Canada (I live in the United Arab Emirates). But it copies everything I do. Im dead and seriously when I say everything. I could stay awake all night and write a list of things he copied me, but here are a few:

Converse: shoes. No one at my school wore (they werent popular in the UAE, as last year). Now, almost everyone in the grade door em, because I bought a pair, then I copied, and then others copied him etc.

Guitar: I play guitar. I told him I got a Les Paul for Christmas, and surely enough, so he did, even if he cannot play.

Battery: I also play drums, and now he wants to learn.

Band: Im in a group. Guess what? Hes starting a band too, once he learns to play the guitar .... WTF?

Quad: It's like a 4 wheel motorcycle. I had one two years ago, a Yamaha Raptor. Sure enough, a month later he got a quad too, but it wasn't the same as mine. Now, he told me recently that he was trying to convince his mother to buy a Raptor.

Expressions and insults: It really made me shit all the time. Hes still a copy to my insults, so my returns, he even uses my back against me. I tend to use expressions much in one week, then another using different. It still uses the same that I use. Ditto for msn talk and icons. I use the "+ o (" icon a lot. Whada now you know? He uses it like every two minutes. Even with smileys, etc.

Rip Stik: I had this wave board of Toys R Us's called stik RIP. I taught him how to ride mine, because he was harassing me. The next thing you know, he has one.

Socks: This isn't a big but still. in 5th year at the beginning, we both used to wear our socks, like all the way up. when I started to roll down and wearing shorter, so he did.

Music: At first, it was Linkin Park. I liked them, he didn't even know them when I asked him. I said OK, he said that was my favorite band and that's all. The next thing you know, her favorite band. same thing happened with Green Day recently. He knew, because I asked him and he said he didn't like them much. So I said oh ok, theyre my new favorite band. And guess what. The next thing you know hes IN LOVE with Greenday.

PSP: I have a PSP. He got a PSP.

iPod: I have an iPod Touch, he got an iPod Touch.

Hes same fate with my ex girlfriend!

These are a few things. He also tries to dress like me and things. What I can do well for him to get my point of view? I just want to make him understand that hes a great guy, and when he tries again, it has a really good sense of style. And it should be his own person, do not copy me all the time. What pisses me off also, however, is that he has a little sister who is like 09 I believe, and it copies everything he does. and hes always complaining (he speaks shouldn't). But shes copying me, because it does what I do. She has a stik RIP, shes get a guitar, she wears converse, shes get an iTouch, she got the stereo system as well as him (that's another thing, he copied me) and she apparently likes greenday too. she got a quad. Basically, it pisses me off that copy me a bit, but the reason I want him arrested, because it copies out of it, then it copies its neighbor, and next thing you know, everybody / disposal. Any ideas how I can make it stop? I do not want to be mean, but were best buds. Btw, sorry for ranting! Thank you

First, let me say that as annoying as it may be "imitation is the sincerest form of flattery"
Now that we have that road, sometimes things seem more cool when people realize that we love. It may not be copied on purpose (although it does.
