Take a breath

Air serounds  you and hugs tight around you. You breath it in then breath it out to something else. It follows you were ever you go, creeping on you day and night. Making no sound but maybe a little wistful while it's pushed through the door. Undetectable with out being able to see but it's there and always is. without is we humans die and with to much of it we would die with a pop. Something we need and don't think much about nor see, air.
