Being Rich?

(I'm not trying to brag I just need help) Well at school people always know me as the rich kid. My dad own's his own compnay, I live in a big house, wear expensive clothing, drive a Mercedes. How do I get kids to stop calling me rich kid. I hate it!!! I keep telling them to stop but they keep on saying "Why don't you just shut up and go buy something with daddy's AMEX black card!" It is so annoying and I really hate it. I'm not snobby or I flaunt what I have. My mom just pulls up in a SL500, in a Gucci dress, wearing Christian Louboutins. HELP ME PLEASE!!!!!!!
