take advantage of me

i'll share all your diseases,
take your day out on me.
i'll kneel before you,
tell me and i'll do it for you.
i'll go away when you want,
take all of me.
i'll let you yell it out,
thrown down at your mercy.
i'll shut up when it's your turn,
tell no one your flaws.
i'll still love you when we're old,
then i'll serve you more.
i'll always be in the mood,
take advantage of me.
