With time...J.L.Borges

After a while, man learns to perceive the subtile difference between to support and to chain a soul and learns that love does not mean that you sleep with someone and having someone next to you is not synonymous with safety and so, man begins to learn ... that kisses are not contracts and presents are not promises and so the man begins to accept defeats with his head up and eyes open and learn to build all the roads based on today and now, for the land of 'tomorrow 'is too uncertain for plans ... and the future always has a lot of alternatives, which stop halfway.
And after a while, man learns that if too much, even the life-giving warmth of the sun, burns.
So he  begins to plant his own garden and beautifies his own soul instead of waiting for someone to bring him flowers, and learns that really can support, as indeed has the power, that's really valuable, and humans learns,  learns ,... and learns each day. 
With time you learn that to stay with someone because it offers a good future means that sooner or later you will want to go back to the past. 
With time you understand that only one who is able to love you with your flaws, without trying to change you, you can bring all the happiness you want.
With time you understand that true friends are not counted and the one who does not fight for them sooner or later it will be surrounded by false friends. With time you learn that words said in a moment of anger, can continue to make harm the rest of your life . 
With time you learn that the excuse is something anyone can do, but forgiveness it is something  really big hearts can do. 
With time you understand that if you seriously injured a friend, is very likely that his friendship will never be the same intensity.
In time you realize that although you are happy with your friends in a day you will cry for those you let them go.
In time you realize that every experience lived with each being, will not ever happen again.
 In time you realize who humiliates and despises a human being, sooner or later will suffer the same humiliation and contempt, but multiplied square.
With time you learn that if youhurry or force things to happen, in the end, they will not be as expected. 
In time you realize that in reality, the future was not the best but when you are living right at the moment.
With time you will see that although you feel happy with who you are around, you will miss the ones that were with you yesterday and they went and are no longer here ..  
With time you will learn that trying to forgive or being forgiven , to say that you love, or that you miss someone, to say you need, to say that you want to be friends, before a tomb, has no sense.
  But unfortunately, all is learned only with time ...
