Might be a COIN.
It is a coin
My head and tail both equal are, My middle slender as a bee. Whether I stand on head or heel Is quite the same to you or me. But if my head should be cut off, The matter's true, though passing strange Directly I to nothing change. What am I?
I used to think that I'm important But now people tell me I'm not. I can't even control where I'm going. But I'm quite sure that it's not hot. I cut in front of other shapes, Going towards the light. Now tell me, who am I? While I wait in everlasting night.
