Liar?

Oh, who am I now? Tell me! I demand an answer For is it not you Whom has shaped My entire way of life? An influence Not dared challenged Why do you sit Motionless- In ignorance and bliss Sing with me a tune Won't you play With me once more Or shall you fool Strangers and friends Alike, with tall tales? Ah, but I know you Well enough to see And taste, your distaste Never have you seen This before- and never Will you see this again I find myself unable To resist the urge To throw stones While we are trapped In a glass house
