帮我看看下面这片短文的语法有没有错误,英语大师帮帮我看看
Dear grandparents,NOV 27th 2009
First,warm wishes at Thanksgiving.
I'm sorry that I didn't say "thank you" yesterday.I was so busy yesterday.And I wish it won't be late.
why didn't you call me?You promised that you will get back to me.In the past days since you went to the US,I was always waiting for your call after the dinner while I was watching English programes.
I have already finished my middle-team exames.I did OK this time,And I also got"A"in my listening test.I can read the English book which you gave it to me without dictionaries.That's what both you and me want.I only just made it to you.
Wish you all the time
Thanks in Thanks Givingday
