I ever hang over the throne where you sit, forced there by flattery and lack of wit. I embody the perils of power without peer; a crown may bring glory, but ever with fear. My edge is keen; my promise is true. Name me, who hangs by a hair above you.

From field to flame I change in form. I crack, expand, and make loud noises while I transform. In the end, I've grown in size, but weigh much less. So, what am I? Take your guess.

Your fingers find me in the night,I wait for small delight. A flick, a tap, a shove, instantly, I answer above. I don’t create, I just release or stop the flow and bring you peace. From guest to ghost I guard the door waiting for you once more.

I was born in ancient times, I endure in these days. A horse once accompanied me, before other ways. I can be alone, but four is most sound Man travels with me, for I am too round.

I have a truck, but I do not have a engine. I am often seen in certain parks.
