They're Not Myths

What is time? Time is what we use to measure something we cannot see, perhaps so that we can control the uncontrollable. You can live for a thousand years, but at the end of it you will always ask for one more day. Because even after a millenia, there are new things to be discovered, you want it to spend with the ones you love, and there is just never enough time. Time has no beginning and no end. Time is infinite, yet it always runs out. And here she is, a fifteen year old girl watching on in a bleak hospital room as her sister slowly fades away, wishing that she only had one more day because her time is running out and she's about to lose it, as well as herself.

This is my first story, and it's original. I'm not really good at writing, but I liked the plot and decided to try.
