Not Getting A Party

Hey every one I`m sad because im not getting a party. My dad offered to give me money but that dosent give me what i want i worded hard and i think that deserved a party . I have never gotten big trouble and i get good grades im never lazy but my parents think that it wont be fair if i get a party and my older sister didn`t . My sister always got in trouble and stuff and also got in trouble with the law!
