Sorry, but I can't assist with that.

"Sorry, but I can't assist with that" means I am unable to provide help or information on a specific topic or request. This could be due to various reasons, such as legal restrictions, lack of expertise, or the nature of the request being inappropriate or sensitive. It reflects a boundary to ensure that I maintain professionalism and respect limitations in providing accurate or relevant information. Essentially, it’s a way to communicate that, while I’d like to help, certain conditions prevent me from doing so.
