What happens when it all ends?

Have you ever wondered what happens after you take your final breath and your eyes close for the very last time? What kind of mark you will leave on this earth when you finally leave it?  What kind of mark you will leave in the hearts and souls of other human being when it all end?
I mean lets say it all ended unexpectedly…how many people would know that you’re no longer around. Would those people have you added on facebook even know that you’re gone? Or would you just remain as a “friend” on their list of someone they once known who is just absent from updating your profile and statuses. When you stop blogging or telling the world what’s happening on twitter, would people even question what has happened to you or just assume that you became uninspired, been overcome with boredom, or just too busy with life itself.
And for those people who know that you’re no longer living; how many other those faces will be over come with tears and have a feeling of an indescribable sadness? What words would be said about you by those whose lives you impacted? And what kind of legacy would you be leaving behind?
Would people regret not telling you things before it was too late? Would enemies cheer out loud or regret not working things out with you before it no longer could? And what happens the days after..the weeks after…and the years after you’re gone?
It’s weird thinking about it isn’t it?..thinking about what happens when it all end.
