Now, I understand why it felt funny when I read the first sentence.
For somebody who is learning English as the second language, it is not alway easy to see it is alright to omit 'that' or hide 'it is that' and so on, if you know what I mean...
Also, I started to think I need to get used to grammatical terms, such as subordinate clauses, etc. to understand people's explanations better.
There is no short cut to learn any language, is there?
Well, I guess I keep learning.
Thanks again, bob K.
I really appreciate your reply!
