Well my parents are fine, i can't complain,
but there are things that they'll have to explain.
they can't stand my music, my clothes and my mates,
and they nag me for days if i come home late.
but then i say that i've grown up and need my space,
they don't listen. they just make a clever face.
they control me no matter how much i object.
they don't understand a thing about respect.
my parents are choosing who i should be,
but why don't they leave the decision to me?
they never forget to say what they expect,
but what about friendship, trust and respect?
and then they talk about my future and success,
i don't listen because i couldn't care less.
i upset them because i always disobey,
but i hope they will be proud of me one day.
i'm quite cool, my parents shouldn't complain,,
but there are things that i'll have to explain.
i get on their nerves and i drive them mad,
so now is the time to say sorry for that.
but then they talk about my future and success,
i don't listen because i couldn't care less.
i upset them because i always disobey,
but i hope they will be proud of me one day.
