Has your mom told you not to torture the elderly?!

[Ahmadov]

I am trying to post a joking remark for a friend, with whom I am playing chess online. He has a better position on the board and I want to post the sentence. But I am not sure which of the sentences below is the most correct (or correct). Can anyone help, please? Thanks in advance!

1. Has your mom told you not to torture the elderly (this is the sentence that came to my mind immediately, but I thought it might be wrong.)

2. Has your mom not told you not torture the elderly (I designed this sentence to my knowledge of grammar, not my feeling.)

3. Hasn't your mom told you not to torture the elderly (this is another option to let teachers explain where should we have "not" for "has". I have seen different usage of not in such sentences...)

Any explanation is highly appreciated, as officials and businessmen say

Ahmadov, I think you should use the word 'elders' but not 'elderly'. You are not an old man yet.

My humble opinion

[Ahmadov]

[Pamela]

Feminine intuition and nothing more.

Ok then, Zahir.

[Ahmadov]

So, what do you think about the sentences? Nobody wants to comment on them Or are they all correct?

Only the third sentence ( showing,perhaps, surprise, reproach--depends on the intonation). The first one has a tad another emotional colouring. Do you understand what I am driving at?

Has your mom told you not to torture the elderly( I 'd say elderly people)?
You simply ask a question, make an inquiry.

That is how I perceive your sentences. It would be better to wait for other replies.

Thanks Pamela!

[Pamela]

Spot on!

Thanks a lot, Amy!
Actually, the meaning that I wanted to express was the one expressed by sentences two and three. Unfortunately, I have already posted sentence 1, which implies something different

Amy, can you explain the usage of "not" in similar sentences. Where do you think "not" should be in the sentences below:
Have you not read the latest article? //Haven't you read the latest article?

The problem is that I was taught at school that "Haven't" is the right form, i.e. we should use "not" immediately after "have", but I sometimes run accross the other usage as well, where "not" is used before the verb in present or past perfect.

Pamela and Amy,

The penny has dropped! Now it makes sense why my first sentence is different from the other two...

Thanks for your help...
