Tagline: Why bother about shutting down your laptop when you can just close the cover and leave it to sleep and hibernate.
The great thing about sleeping and hibernating is that, Everything you just left behind will still be there no matter how long it takes for you to continue work the next time. The data will still be there. You dun haf to re boot and wait for it to start and then do whatever you haf to do over again. Find the same website, do the same procedure... Etc, etc. You can even save the time on logging in to websites!
Sometimes wish human relations were like that. No change at all. You continue where you left. Nothing new or changes will get in the way or be added into it. But I guess, it's not possible. Once it ends, it's time for a change for both or more parties. You haf to make an effort to pick it up. Going back to where it's left or where it's started, hmmm, seems like a dream. Best option? Leave it, drop it, and forget about it.
