引用文章千錯萬錯都是我的錯--懺悔書

it's my fault that i can't convince you to use my way to teach kids

it's my fault that i can't use more gentle heart to teach kids

it's my fault that i feel so helpless that i can't find my way out

it's my fault that i don't have more wisdom to solve 21-year old stuff

it's my fault that i am so limited that i can't change everything but myself
