Answer:
I look like a tiny trombone
People need me yet they give me away every day.
I begin and have no end. Eventually, I will be the ending of all that has begun. What am I?
I have no head and a tail I lack but I do have arms and legs and back; I inhabit the palace the tavern the cot 'tis a beggarly residence where I am not. If a monarch were present (I tell you no fable) I still should be placed at the head of the table.
If two is company and three is a crowd, what is four and five?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
