Cry of Please

Hand me the Valium please
Because I like to be polite
I mind my Ps
And if you please, do you as you please
Because I like to be polite
Put a bullet through my head please
Because I like to be polite
I spare you my mess of mind
And if I may, say as you please, please
Because I like to be polite
Let me nap for a bit please
Because I like to be polite
I'll be quiet I promise
You'll have peace, for as long as you please, if you let me please, please
