Parents don't get the pix before they speak

Actually I was in relatively good mood today. Then after dinner a question just popped out of my head: Is a computer a want or a need to me? I went to ask my mom. Then she kept thinking that I wanted a computer as I needed it for something. Then I TSK and went back into the room and continued using the computer. After that she entered the room and said(more like a shout-say voice) that I wanted a computer because I wanna go surf the internet watching videos. For goodness sake, hell months ago SHE was the one who initiated the idea of getting a computer for ME. Now SHE says that I am using it for CRAP STUFF. I can't understand this. And I've got nothing to do, that's why I'm watching videos right! If not stare into the screen? Tsk. Then she just went on and on like a machine gun. So I just ignored. Please get the pix before you speak dear mom. -.-
