First off, It's 'You're retarded', Retard.
Secondly, You're 16? So? Most 16 year olds where I live have jobs and work part time (after school and durring weekends in the afternoon).
Thirdly, Congratulations you were planned, who cares? I was as well?
Fourthly, My parents have raised 4 healthy Children, me, the oldest took the responsibility to help my MOTHER WITH THE BILLS because she couldn't pay for 6 on her own check. What does parenting have to do with anything here? I moved out on my own, I got a job on my own because I saw my mother struggling and wanted to help.
Fifthly, "Leeching" is when you abuse the income of your parents (no matter how large or small) by not properly using the education they're providing you (By the looks of it, you really AREN'T), Sitting on the computer all day long playing this shit game trying to act cool instead of getting a summer job and have a life, Not being grateful of what your parents give you (Have you thanked them for all the times they've paid internet for you? Doubtful). It's they're job to provide you, but it's also your job to acknowledge how hard they work and actually step up and do your own.
Sixth, Aren't you "Retired" Why do you keep posting?
