I made a comment on this question:
My mom is being "nice". But it's unwanted. How do I get her to stop?
I had some advice and started writing an answer, but after starting to write it out I realised I couldn't answer in a solid way without getting more info from the asker. There was already a comment from another user requesting more information so I deleted my draft answer and instead just put the friendly advice in a comment.
I understand that we shouldn't answer in comments, but as I just said, it wasn't really an answer at this point as we needed more info to make a decent answer. But even though it was just a tiny bit of suggested advice, it was a suggestion based on the question, so I think it was worthy of offering it, albeit in a comment.
My comment was deleted within minutes. Why is this please?
