You gave me more than 12 years of love and endless joy but in your 12 years with me, I only gave you at most 3 years of attention and love. I have always taken your love and attention for granted. You never complain but instead always returned with yet even more love for me. 

Now that you are gone, life will never be the same again. Baby, I am sorry for what I have done, or rather, had not done. I regretted not spending enough time with you but I know it's too late to regret...

Baby, I am truly sorry.
