The Line

 One can't uncross a line for it has already been crossed.

Though life seems to be a game with variety of levels, you will be unable to come back and play the previous one once a certain point is reached. It is similar to those biography movies; you won't be able to play the previous scene again once the episode is shot. There is no UNDO button, neither CTRL+Z nor CTRL+Y will make any difference, as you will be hopeless in your endeavours intended to change anything.

As soon as a certain line is crossed, whatever you leave behind becomes a rigid past; those are just various memories encompassed in the pages of books and lines of favourite songs. The thing is you won't be able to change anything, neither you will be able to read those books again nor listen to your favourite songs for they  are left in the righteous reality of past.

Facing the line and crossing it make you insensible, as someone cast a spell on you and the feelings you have are circumscribed. 

You do not feel the way you used to, 
you have left behind the part of you, 
you seem incomplete, 

you seem hollow…

You look for a way out but is there one?  The certain thing is  - going back is an unfeasible mission. You need to embrace the reality;  the reality where a part of you is stolen, a part of you is no longer the same as if you are diagnosed with retrograde amnesia and all the hopes you were carefully cherishing are impossible to be recalled. Something seems broken and incomplete but the thing is you no longer remember how it felt to be complete…

There was a line!
