Write a composition after reading the passage and write back to grandpa for the children in the article.

I'm sorry. Please forgive us! Because we went back that day, we were too busy studying and our home was so far away, so we didn't remember the fact that we came to see you. We didn't remember until we received your reply.

I hope we can see you again next autumn!

Love you: Meimei, Xiaoxiao, Lolo.
