We will never know what will happen next moment

you must wonder about the title of this new post and i will tell you the answer. I have been in a bad moon since i was told by my mom that my grandfather was in the intensive care unit yesterday. He could hardly breath because his lungs are sick. So I went to home as quickly asi could to take care of him but his condition is still not so optimistic. Well, I think that we should treasure what we have now because we will never know what will happen next moment.
