Blank

Everyone have a space which for the another one...
It is the BLANK at the first at all..
but when someone come, he/she will fill in it with love and care..
when he/she leave.. the space is blank again..
i wonder, actually.. it just like fill in the blank..
why cant just left it blank and wait until the most SUITABLE answer to fill it??
coz.. when keep rub and rub the answer which not suit will hurt, isn't it..??
就因为空虚而不舍得放下。。hmm...
HAHA..
continue my study~
