Why can't I.

because you want to forget that guy... Trying to forget someone is remembering and recalling that guy all the time... We are Heroes in our story... We want to face the strome like a big tree... But if you see the big tree... You can see its he who suffers the most... But look at grass... Its very neglected... And strome also neglects it... So if you want to forget pain then dont fight with it... Just go with it... Think sorrow as other emotions... Like happiness anger etc...
