回复：谢谢指出病句。让我想起有些他们日常说的 I go get it等句应该是病句吧？

For writing spoken English, I'd like to recommand Herman Melville's "Moby Dick" - the greatest American novel.

In terms '"Yes I was so busy. " I explained.', the misleading word is "Yes", which negates "didn't" and leads to the impression that you had said "hello".
