The meaning is If you miss someone special when they arent there, you have no air. It reminds me of my boyfriend Austin Myers because when he is not there right by my side, I have no air, I can't breathe. So Austin If you ever see this. I love you so much:-)! I don't want anything to happen between me and you because you are my everything. I love you from the bottom of my heart and I will never do anything to hurt you in any kind of way because you mean so much to me. Day or night. Sleeping or awake. Never means I never stop thinking about you because I don't, and that's the truth.
