How do you know that you really know someone?

... I would say you never know because you never really get to know someone.

As in the friendship, love, workmates... as even family, at the end, something happens which
(bad) surprises you.

That girl who was your best friend in the school for years, who knows "everything" about you: your problems at home, in the school, with other friends... and with guys... at the end, that friendship can break off and both of you take different ways... so different that you loose the contact. Sometimes you don´t want and you try to recover the wasted time, but how? how are you going to be the one who makes it happens?... You don´t do it because you realize that person is not who you believed.

And what's about that guy you were deeply in love? the guy who built your hopes up and failed to keep his promises?... For sure, you will cry like never before for longer, but the pain finally will go away.

In despite of this, trying to know people is one of the most interesting things we can do. Of course, you cannot, and you must not, show yourself totally to everyone, but you must try to make the most to learn and capture the essence of the others because it will be one of the basic things which makes us to grow as person and everyone has got some small (some of them "great") peculiarities which make them unique in the world.

So, please, open your eyes, smile people who you see and if you have the ocassion to speak to them, pay all the attention you can because for sure you will get something from them which will last and make you a best person... although you never see him/her again and you never get to know him/her.
