Hi,
I guess I might as well ask another question I have in this thread: It would make life simpler if you started another thread, I think. It makes the discussion easier to follow, and to respond to. OK?
Eg)
I had been eating when Bob arrived.
I was eating when Bob arrived.
The "was" and "had been" are both past perfect, are they not? Because if "was" is meant as a past simple, that wouldn't make any sense at all! However, I've seen "I was eating when Bob arrived" used as an example of past perfect in a grammar book before. I think you misinterpreted what you read. 'I was eating' is Past Continuous', not Past Perfect.
What's the difference between, "I had always been very shy as a child" and "I was always very shy as a child"?
#1 is Past Perfect. It refers to a time in the past when you had the result of being shy as a child. eg "When I met Mary, I didn't know what to say to her. I had always been very shy as a child".
#2 is Simple Past. It just states a fact about the past.
or in this example, . . . I think the same comments would apply to your next example, although I don't find your meaning completely clear.
If you have more questions, please start a new thread.
Best wishes, Clive
