Question

your parents entrusted you with the task of looking after your dog as they had to go out of station. since you were busy,you happened to neglect  your dog,unburden yourself and your 
feelings of guilt in the form of a diary entry.  

Answer 1

Today I'm not feeling so well I'm feeling guilty about my mistake and promise never-ever to repeat this mistake again.
Today, in the early morning my parents went out of station. Before going out they gave me a responsibility-to look after my dog. They trusted on me that I will take my responsibility. But I broke their trust!
I was too much busy in doing my homework and other works that I could not give food and morning walk to my honest dog. My dog was waiting for me all the time but I could not help him! He was hungry for a whole day and was sitting in cold surrounded by water.
Now I'm feeling bad that  because of my irresponsibility my dog had to suffer! But I will never repeat this mistake in my whole life!
