i'm not sure how old this kind of stuff start to happen but , but i can only say that there is some time in our lives that , we don't really care about people that much ,we just live by , don't get too much attached . i guess somehow in a near future ,we realized that some people are just too important to let life happen and take them away . just like always . So in a way , if we are smart enough ,we realize that there is something we gotta do , to change that . some things to do and get back where we were , but first , some other things to finish up . does it make any sense ?
