I certainly wasn’t being nasty. I haven’t read every post, but I haven’t seen anyone being nasty to you either.
In person, there is more information; your tone of voice etc
But in writing, there needs to be some rules. Otherwise it’s sometimes difficult to be clear about what you are trying to convey.
No malice or unpleasant criticism involved.
In your head, you know exactly what you are trying to say. But the way you have written it is confusing. @grain made a summary of what they understood, but you haven’t acknowledged that post, so we are none the wiser.
