since ....

[azam adullah]

I have some queries to discuss.
Is the statement below passed?
You are looking better since you were back from the north.

Also, I stumbled across the use of past perfect tense with preposition "after" to make one event background. the book states:

1. Adam screeched after he had seen a rat. (the seeing event here is background)
2. Adam screeched after he saw a rat. (here, the seeing event is foreground)

However, I have a doubt about it. I think there is a typo in the book.
I guess, the seeing event in sentence 1 should be foreground, whereas, the counterpart in sentence 2 is background. For the reason that past perfect tense lays stress on the completion of the action in after-clause. Am I, or the book, right ?

I don't see much of a difference between these two sentences, except that the first one seems more cumbersome. I'm afraid I don't understand what the book is trying to say here. Perhaps others can help.

It would also seem more natural to say that he screeched "when" he saw a rat, rather than "after." The use of "after" makes it sound as if a little time passed before he decided to let loose with a screech. That is not how it happens, at least in my own experience!

You are looking better since you are/came back from the north.

You are looking better since you returned from the north.

I think the following sentences are right.

1. Adam screeched after he had seen a rat. (The event happened yesterday (or sometime ago but you are not on the scene while telling) and you are telling someone about it now.)

2. Adam screeched after he saw a rat. (You are telling someone about it while on the scene.)
