Sorry dad n mom

sorry dad I'm live up to your expectations,
I cannot do your child the perfect,
I'm not so smart sister,
In SPM me cannot take 1 A to you,
In home me cannot help you to all,

I'm always let you worry about,
I'm always live up to your expectations,
I.m always make you sad,
I'm always make you angry,

Sorry dad n mom I'm cannot do perfect...so so so...sorry...
