I am something that you own, but you hardly ever use, while others use it daily.

I am born from the heart, but I do not come from your dna. You feel me when you are around your closest people.

I can create height, but I cannot jump. People use me to bounce.

I arrive to ruin the fun, Before the show has even begun, I beg for eyes, for ears to hear, Yet all just wish I'd disappear

I suddenly appear in your head, once I’m there I am hard to remove, In a silent room I can be deafening.
