Book

I've came to believe that it is not;

don't judge a book by its cover.

But it is better to say that;

don't judge a book only by its cover.

because:

sometimes you can tell the personality of a people only by observing his/her physical.

yet, what inside sometimes will be portrayed outside.

obviously i am not a clean-type person if i'm smelly and my dress is dirty.

right?!

but:

not all the characteristic of a person will be portrayed physically.

you can't tell whether a person is brilliant or not only just by looking on his/her face.

yes, it may work on someone, but not at all time.

that's why i say;

don't judge a book ONLY by its cover.

but still;

you can judge a book by its cover.
