How we take our lives for granted and don't cherish what we have until we have it no more.
We long with every heart beat, breath and tears to have it again. Your hearts break cause you want to hold and love them but can't.
It is like torture cause you close your eyes, it is right there in your grasp, than reality hits and your eyes open and you know they are out of reach.
Now it is when you wished you would of said the words you longed to tell them, and didn't and now you can't. Than you sit there in torture wishing you would of did this or didn,t do that.
The only thing that you can do is embrace the memories until you are reunited, when that happens you will from now on cherish every moment and say the words you long to say and no longer take things for granted but embrace every moment like it is your last.
