parents

well....its been 19 years living with them....n i still thnk they dont understand me.
Well i know every teenager thnks that his/her parents cant understand but this is lil different.
i do a small stupid mistake n my parents say that im of no use...wont be able to do anything in life except blaming people.
and im left asking myself is that true?
am i that useless?
am i that big shame to my parents?
i never thought my own parents who mean the world to me would ever say that to me.
n its not that happened 1st time it happens everyday.
i never get my answers...because deep down i know i am not useless...i am a girl capable of doing many things.
but howcome parents can thnk that their own extension is useless and good for nothing will remain a mystery to me!!
