| Dear grandma, How is it going? I hope that grandpa is 1 now. I was sorry to hear that he had a 2 last week. I hope you are in good health. Things are fine now. I finished my end-of-year exams last week and got my 3 card today. I always get 4 when I see the envelope from school in the mail, but 5 I did OK this time. I had a really hard 6 with science this semester, and I wasn't surprised to find that my worst report was from my science teacher. She said I was lazy, which isn't 7 . It's just that I find science really difficult. 8 disappointing result was in history. My history teacher said I could do better. The good 9 is that my math teacher said I was hard-working. And my Spanish teacher said my listening was good. Well, that's about all the news I have for now. Dad and Mom 10 their love. Love Alan | ||||
