I sound like I'm a man who's been kissed by the sun. I'm featured in a subject many consider unfun. Our paths will not cross, but we'll meet at one. Oh by the way, do you like puns?

I am naught but a border, particularly for figures of geometry. circles adore, the rest general bore me, so unscramble this word for a jest.

When one door closes, I come knocking. Some people catch me, some people let me slip. I’m hard to find. I’m hard to make. I’m taken for granted when fear takes place.

A word I know, six letters it contains, remove one letter and twelve remains. What is it?

I move your hand but leave no trace, I’m both your prison and your grace. I vanish the moment you’re forced to choose, Yet I’m the very power you fear to lose. Kings can’t command me, gods can’t refill. Name the quiet rebel ruling you still.
