Not my fault I have trouble paying intention in school.
Not my fault that I'm dumb.
Not my fault that I'm incoherent.
Haha, yeah it is your fault. Don't be such an ignorant little brat. I'm starting to doubt too that you're fifteen.
You're going to get nowhere in life if you keep blaming everyone for everything else and whining about everything. If you are fifteen, there must be something mentally wrong with you and I suggest you visit a doctor of some sorts.
