[General] while I am around vs not while I am around

[ZinLada]

Is it possible to say: "Don't do that, not while I am around."

If it is correct, could you, please, explain whether there is any difference in meaning with the sentence below?

Don't do that while I am around vs Don't do that not while I am around.

Thank you.

Welcome to the forum.

The original sentence is OK but would be better with a dash or an ellipsis (three dots) instead of the comma.

The second is fine but the third is not.

Thank you.
So it should be:
"Don't do that while I am around vs Don't do that.. Not while I am around."
Could you explain whether the sentences above differ in meaning. I mean, can we substitute the second one for the first one and vice versa?
Thank you.

I said three dots - not two, and it's incorrect to capitalise the next letter.

The second is slightly more emphatic.

Thank you for your reply and correction. As for ellipsis, it was a typo.
