The day that will never come.
There will be a day when you will only want to be with yourself, you will see that girl’s smile and will think “It’s really beautiful” but you will not want it for you.
It will be something like to see the most beautiful flower in a garden and not picking it because as much as you see most you will find defects, the flower will dry, as your feelings for her;
You will not need to worry about the flower health, feelings, desires, you will keep walking, only that, it is beautiful and you are walking.
In this day, you will already know about pain, but you will know about love too, you will know about what you need to survive, to be happy, to be yourself.
The problem is that you probably will want to die.
