When I was small, 
  I tell myself not learn to regret. 
   
  In my 23 years of life,
  there are 4 things that I thought,
  I would never  regret. 
   
  As time passes, 
  as I grow older,
  I begin to regret for what I did now. 
   
  If there was a chance,
  to go back to the time that I proposed to her,
  I would give myself two slaps 
  and suppress my feeling to her. 
   
  As time passes, 
  as I grow older,
  I learn it’s not easy to learn not to regret. 
   
  I may this become a scar on my skin;
  I may this become a part of my memory;
  I may this live with me every day;
  to remind me that I will regret too.
   
  I shall never say I will not regret,
  I shall think before I do anything.
   
  As the storm pass, 
  as the fight over,
  everything cannot just undo.
   
  The only thing that I can do are – 
  I wish she stay happy all the time;
  I wish she find her life partner.
  
As a small reminder, I choose this song to remind me that never ever say that I would not regret to do any decision.
