Day 29 Today is the end of the writing challenge. I understand I forget most of the grammar because I have not studied grammar for 6 years. I never think after 6 years without study my grammar becomes so awful. Thanks a lot to Barbara for this challenge. Now it is better to start study more books in English especially grammar books. P.S. of Day 29 The reason that causes I chose diarrhea for my thesis was, I chose one of my teachers from my university for a supervisor and she accepted. She gave me some object to research but after 6 months she said “I couldn’t be your supervisor”. After 3 months I found a very good professor as my supervisor outside of my university. First, he asked me about my interest but my interest object was so difficult to work on it in Iran. He recommended the topics about diarrhea. I had to accept this topic because if I wanted another topic, maybe I couldn’t defend my thesis in time.
