..I don't know and I don't care..

Have you ever felt like you wanna punch someone really really deeply hard?! Because of what he / she had did to you? And you just wanna yell at him / her loudly like "Hey ya know what?! Whateverrrr!" I really sick of all those stupid things (true or untrue things) that made me pissed of and tired. And the only thing that i really wanna say and can say is : I don't know and I don't care!
