I’m born in silence, but I can shake a room. The more you share me, the less you have. I can warm a heart or start a war. What am I?

I am certain but unscheduled. Everyone moves toward me, yet no one arrives early. I end all questions, but answer none.

I grow louder the longer I stay. I break when spoken, yet I’m never truly gone. I can be shared without sound.

I answer when spoken to, yet I have no voice of my own. I follow you everywhere, but disappear when you get close.

I never spoil, though ages pass me by. Made without hands, yet crafted with care. I come from flowers, but I’m not a bloom, and once I’m taken, the makers must work twice as hard.
