Dear Anna,
I appreciate your sincere friendship. You have help me so much yesterday when I was upset with my grade. Thank you for your encouraging words. You truly know hoe to comfort me when in times of need.
Yesterday was very confusing because I could't finish my examination at all. I was only half way there. I studied and prepared well, but I still couldn't understand the concepts. It seems unfair, and I don't deserve to fail that test
Thank you for your help. You're the greatest friend a guy could ever have. I hope that life will treat you well as you take your examinations. I'll support you too. Good luck.
