I imagine you have your reasons for wanting to say this.
Please don't talk to me.
Could you please not talk to me. (This sounds like you've already asked the person to not talk to you, and yet they keep trying to talk to you - this sounds like a repeated request.)
Don't worry. I would not say this unless there is absolutely nothing more civil I could do about a situation. Just to make sure it's not a typo...Is there a question mark (?) at the end of 'Could you please not talk to me' ?
Thanks for telling me about the missing 'you', Huevos. I don't know why I tend to skip words when I type recent
